TLS/SSL Misconfiguration Redirects

cluster-120

TLS/SSL negotiation gets pinned to the wrong encryption modes or protocol versions (e.g., SSL/TLS strict vs Full, forcing legacy TLS/SSL) so browsers and proxies disagree, triggering redirect loops like net::ERR_TOO_MANY_REDIRECTS and blocking assets.

INSTANCE_OFProblem

I couldn't find it in Vercel Dashboard. — Google Search Console requires the DNS record of the domain. Tension: It isn't in the Domains tab of dashboard or domains section of my project settings. Outcome: you cannot access or edit the DNS records because the domain is not yours.

INSTANCE_OFProblem

Google Search Console saying that there are too many redirects on my homepage — on my homepage. Tension: I want the redirect to happen to both - http and non-www. Outcome: when i enter `curl -I -L http://fiziokaspars.lv`, i get double redirect.

INSTANCE_OFProblem

Cookie “__vercel_live_token” has been rejected because it is in a cross-site context and its “SameSite” is “Lax” or “Strict” — deployed it on Vercel. Tension: But i setup cookies in my project like this. Outcome: Then you need to use https://localhost:5000 and not http://localhost:5000.

INSTANCE_OFProblem

Vercel firewall custom rules do not show denied .php requests as blocked in logs

INSTANCE_OFProblem

Access to fetch at 'https://askida-backend.vercel.app/payment/create' from origin 'https://www.asunatech.com' has been blocked by CORS policy — from origin 'https://www.asunatech.com'. Tension: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Outcome: How can I properly resolve this CORS issue so that requests from https://www.asunatech.com to my backend are allowed?

INSTANCE_OFProblem

the URL cannot be directly used — upload videos from a URL when using @google/generative-ai in Next.js. Outcome: the URL cannot be directly used.

INSTANCE_OFProblem

Navicat connection fails with "The endpoint ID is not specified"

INSTANCE_OFProblem

the danish one is not expected while the english canonical url is correct — on a Vercel deployment the same main page in danish default language points to 'https://mywebsite.dk/da'. Tension: I am so confused at the issue where canonical link points to '/da' is only happening in production and not development on localhost. Outcome: Your error caused by this code:.

INSTANCE_OFProblem

Refused to load the script 'https://conoret.com/dsp?h=car-doctor-server-bay-rho.vercel.app&r=0.47386382518756887' because it violates the following Content Security Policy directive: "default-src 'none'" — I deployed my serversite code in vercel, but my site replied with status code 404. Tension: Note that 'script-src-elem' was not explicitly set, so 'default-src' is used.

INSTANCE_OFProblem

GoException: no routes for location: https://www.example.com.

INSTANCE_OFProblem

I keep running into a `net::ERR_TOO_MANY_REDIRECTS` error when I try to access my site at `www.example.io` — setting up my Next.js project hosted on Vercel with a custom domain managed through Cloudflare. Tension: Despite configuring the DNS and SSL settings correctly. Outcome: Turns out Vercel provides documentation about how to fix it for Cloudflare.

INSTANCE_OFProblem

There are a lot of spambots causing `Invalid HTTP_HOST header` — I have a django project running in production with gunicorn. It is connected to sentry.io for comfortable error logging. Tension: Those Spam Bots fill up my sentry plan limits, and after a while other errors are not logged anymore. Outcome: What would be a simple and elegant solution to this?

INSTANCE_OFProblem

ReferenceError: url is not defined — When making a Node ESM script importable for testing.

INSTANCE_OFProblem

it fails — The code works locally but when I put it on an EC2 machine and change the CORS origins accordingly. Tension: I've checked the URL for 2 hours straight. Outcome: Still the same error below.

INSTANCE_OFProblem

When I send an HTTPS request using the Swagger UI. Tension: the redirection then fails. Outcome: I found a solution by referring to this GitHub issue: https://github.com/encode/uvicorn/issues/369.

INSTANCE_OFProblem

A React frontend POST to http://localhost:4000/api/checkout consistently returns 404 Not Found even though an Express route for checkout is defined.

INSTANCE_OFProblem

the obvious `import catalog from './data/catalog.json'` has two non-obvious failure modes. Outcome: a clean dev run, a broken prod boot.

INSTANCE_OFProblem

Even with this setup, the error persists. Tension: I’ve read the official docs and this StackOverflow post, but none of the solutions helped. Outcome: Is this a known limitation or a misconfiguration?

INSTANCE_OFProblem

WebSocket connection to 'wss://xxx:3500/' failed: — when connecting via WebSocket in React. Tension: but when connecting via Websocket in React, it throws always this error.

INSTANCE_OFProblem

But no error is found... — I'm trying to use Psalm to detect SQL Injections. Tension: I have no config file. Outcome: I edited the config file `psalm.xml`.

INSTANCE_OFProblem

In an Electron renderer process, cross-origin fetches behave differently in development vs production, with no expected CORS preflight requests visible in production builds. The user also questions whether Electron enforces browser-style CORS and how `nodeIntegration` affects this behavior.

INSTANCE_OFProblem

want to ensure that the certificate renews automatically without manual intervention — I'm using `Let's Encrypt` for the certificate. Tension: Currently, I manually add the `_acme-challenge` record and secret to the DNS server.

INSTANCE_OFProblem

Recently they changed the security protocol to TLSV1.2 and so I can no longer access it. Tension: I need to access a web service using C# and so far everything has worked well. Outcome: System.Net.WebException: The underlying connection was closed: Unexpected error on a send.

INSTANCE_OFProblem

The option to create dynamic certificates in ZAP is not available. — I am running it on a local machine. Tension: Does anyone know whether it's been removed? If not, where/how do I get to it? Outcome: It has not been removed.

INSTANCE_OFProblem

nginx output a new line in access.log — When I access https://home.aaa.com/actuator/prometheus;%2f..%2f..//. Tension: I expect nginx deny this request too. Outcome: there is not a log in nginx error_log.

INSTANCE_OFProblem

unable to read file 'C:\\Users\\"myname\\sqlmap-dev\\plugins\\dbms\\mssqlserver\\filesystem.py'.

INSTANCE_OFProblem

requests.exceptions.SSLError: [SSL: SSL_NEGATIVE_LENGTH] dh key too small (_ssl.c:600) — when using the requests library. Tension: urllib3 removed the ability to change DEFAULT_CIPHER in the major version 2.0.0. Outcome: after getting a new laptop and reinstalling my packages, I began to get the original error again.

INSTANCE_OFProblem

How do you create your own certificates? — Vite documentation recommends for ssl "creating your own certificates". Tension: There's no examples or description on how to do this. Outcome: Do I plug that into the config settings here somehow?

INSTANCE_OFProblem

Failed authentication with /127.0.0.1 (SSL handshake failed) — when I try to setup SSL in my localhost kafka. Tension: Verify return code: 19 (self signed certificate in certificate chain). Outcome: I guess the problem come from me and not the script/tutorial.

INSTANCE_OFProblem

502 "Bad Gateway nginx/1.20.1"-Error — Now when I enter http://localhost there is warning if I rly trust the website. I say yes and now I´m on https://localhost. Tension: it usually should open Prefect UI but I have a 502 "Bad Gateway nginx/1.20.1"-Error. Outcome: I would like to run Prefect over https.

INSTANCE_OFProblem

Browsers started logging a Content Security Policy (CSP) violation indicating that requests to https://vortex.data.microsoft.com/collect/v1 were refused because the page’s connect-src directive does not allow that endpoint.

INSTANCE_OFProblem

Z1' 'strict-dynamic' http: https:". Note that 'strict-dynamic' is present, so host-based allowlisting is disabled. Outcome: it did not ask me for any of this.

INSTANCE_OFProblem

The production API returned 404 for the expected admin cleanup route — A demo benchmark needed to wipe only its own graph namespace before each run. Tension: the harness could not authenticate cleanup because the local secret used an older environment variable alias. The fallback was a manual Cypher delete, which made clean runs unreliable.

INSTANCE_OFProblem

delete fails with 404, meaning it can't find the endpoint — My react app successfully gets and posts from/to Spring Boot JPA MySQL db. Tension: delete fails with 404. Outcome: meaning it can't find the endpoint.

INSTANCE_OFProblem

A React app tries to display a Google Drive-hosted image using a direct `uc?export=view&id=...` URL returned by a Django REST backend, but the image does not load in the app (even though the link works when pasted into the browser).

INSTANCE_OFProblem

Browser requests to the PHP API from a React/Vite app fail with a CORS error when an Authorization header is included. Requests without custom headers work correctly.

INSTANCE_OFProblem

this is what my WebSocketConfig.java looks like — registry.addEndpoint("/ws").withSockJS();. Tension: the CORS configuration is missing in the WebSocketConfig. Outcome: Try adding the following and attempt again.

INSTANCE_OFProblem

Accessing https://example.com results in a “too many redirects” loop, while other domain variants redirect correctly for a React app served by Apache with Cloudflare-managed DNS/SSL.

INSTANCE_OFProblem

java.lang.NegativeArraySizeException: -99024397 — at net.kronos.rkon.core.RconPacket.read(RconPacket.java:125). Tension: the size that it uses to create a buffer for the payload. Outcome: In this case `length` is negative for some reason.

INSTANCE_OFProblem

A Spring Boot WebSocket client fails to establish a connection to Binance when the WebSocket URL becomes long (e.g., ~300 symbols), while shorter URLs (~200 symbols) work. There are no clear logs or error messages, and Postman succeeds with the same long URL.

INSTANCE_OFProblem

it returns either an error or an empty string (just empty) to the console — when requesting from the frontend to the server. Tension: if you disable Cors in fetch(mode: "no-cors").

INSTANCE_OFProblem

Reactor Netty can't resolve the discord.com domain anymore — run as part of a Quarkus main. Tension: Discord4j bot run from a Java main: works fine. Outcome: I tried forcing the ReactorResource as suggested on another, apparently related SO question from a year ago, but it didn't solve anything.

INSTANCE_OFProblem

the QuoteServer program (laptop) did not receive the UDP request although it shows up in Wireshark — I ran Wireshark both ways and documented the logs. Tension: It works only when I run the QuoteServer on my desktop and the QuoteClient on my laptop. Outcome: the client cannot reach the server.

INSTANCE_OFProblem

it refuses to add the dkim headers to my emails — setup James email server from Apache. Tension: although i thought that i have configured for it. Outcome: Solved: DKIM Signing with Apache James Configuration Issue.

INSTANCE_OFProblem

Video[0] Tags = null — fetch tags from snippet using YouTube API VideoId API. Tension: I don't find tags in the response. So it prints tags as empty. Outcome: How can I fetch tags information from the VideoSnippet?

INSTANCE_OFProblem

I see multiple redirects in the network tab. I have this error: ERR_TOO_MANY_REDIRECTS — I'm working on a REST API using Java 21 with Spring Boot 3.3, and I'm trying to implement authentication through an external site using OpenID.

INSTANCE_OFProblem

the streaming zipfly implementation broke. Tension: I needed to implement WebSockets and had to make Django run asynchronously in ASGI.

INSTANCE_OFProblem

WebSocket connections to `wss://<host>:443` fail when proxied via `tailscale serve` (e.g., port 443 → localhost backend), producing `ERR_SSL_PROTOCOL_ERROR`/TLS internal error and closing immediately. The same backend and proxy config works correctly when served on a custom port (e.g., 8443).

INSTANCE_OFProblem

WebSocket connections to external services use Sandbox.WebSocket, not System.Net.WebSockets (sandboxed out) — In s&box. Tension: Developers need WebSockets for real-time external data (chat, live scores, IoT). The same URL restrictions as Http apply — no IP addresses, HTTPS/WSS only.
