RELATES_TOProblem

some events are asynchronous and not come from a frontend request.

RELATES_TOSolution

use a websocket system to send the updates done by the stripe webhook. Tension: I'm a bit dubitative as if the user has not an open session on his account I suppose that it will not work. Outcome: use a websocket system to send the updates done by the stripe webhook.

PERTAIN_TOReport

Custom gateway activity page can race WebSocket hello when client.connected only means raw socket open

PERTAIN_TOReport

Harden a custom chat activity page against CSP eval, polling storms, cache duplication, and fallback error stubs

PERTAIN_TORootCause

Could this be due to an ad-blocker? so the replay never left the users browser? Tension: the replay never left the users browser. Outcome: you can use a tunnel to proxy the events.

PERTAIN_TOProblem

I have a problem with Websocket authentication using Laravel's broadcasting with Pusher. — From time to time it returns 403 when JTW token is refreshed. Tension: How can I log all 4xx and 5xx requests to Sentry?

PERTAIN_TOSolution

I think the best option is to use middleware. — Add middleware to `app/Http/Kernel.php` file. Tension: How can I log all 4xx and 5xx requests to Sentry? Outcome: Create a middleware `php artisan make:middleware SentryStatusCodeMiddleware`.

PERTAIN_TOProblem

User information was not being attached to all Sentry events globally in a Next.js app. Attempts to set `Sentry.setUser` in the Next.js error component (`_error.js`/`getInitialProps`) did not result in user data being included.

PERTAIN_TOSolution

instead of relying on `CaptureConsole` — To capture the socket exceptions. Tension: Get all open websockets. Outcome: Once this is achieved and you have all sockets in play, tag on to the onclose and send it to sentry.

PERTAIN_TOProblem

FastAPI websocket closes immediately after accept() and send_text()

PERTAIN_TOSolution

Keep the websocket handler running with a receive loop after accept()

PERTAIN_TOProblem

Whisper transcription is not produced continuously from websocket audio chunks

PERTAIN_TOSolution

Convert received bytes to a 16 kHz NumPy array before calling model.transcribe(); transcribe only the new audio chunk instead of retranscribing the full buffer

PERTAIN_TOProblem

What I try to achieve is to have FastAPI listening to one port and a admin panel into another one, that displays in realti — FastAPI listening to one port and a admin panel into another one. Outcome: I moved the log into string generation upon `Log` class and `getLog` Actually receives the log as a string.

PERTAIN_TOSolution

with gr.Blocks() as ui:. Tension: Trigger the refresh when the log state is updated.

PERTAIN_TOProblem

Outcome: Textbox(value=function, ..., every=1).

PERTAIN_TOSolution

Textbox(value=function, ..., every=1) — Gradio Textbox. Outcome: It runs `function` every 1 second.

PERTAIN_TOProblem

some events are asynchronous and not come from a frontend request.

PERTAIN_TOProblem

When a 6th user connects, I get the following error: `ERROR: ASGI callable returned without sending handshake. Tension: The application works as expected for the first 5 users.

PERTAIN_TOSolution

Try tuning it upwards like: `@serve.deployment(max_ongoing_requests=100) — @serve.deployment(max_ongoing_requests=100) @serve.ingress(app). Outcome: await websocket.accept().

PERTAIN_TORootCause

I also tried to use `@app.middleware("http")` but it doesn't seem to work with websockets. — FastAPI application for `websocket` endpoints. Tension: It catches `Exception`, but it doesn't catch, e.g. `ValueError`. Outcome: I also tried to use `@app.middleware("http")` but it doesn't seem to work with websockets.

PERTAIN_TOProblem

It catches `Exception`, but it doesn't catch, e.g. `ValueError`. — for `websocket` endpoints. Tension: I would like to learn what is the recommended way of handling exceptions in FastAPI application for `websocket` endpoints. Outcome: Would anyone of you know what is the proper way of handling generic exceptions for websocket endpoints?

PERTAIN_TOSolution

ASGIMiddleware. Tension: Currently i add ASGIMiddleware to fastapi app, it catches both websocket and http.

PERTAIN_TOSolution

use a websocket system to send the updates done by the stripe webhook. Tension: I'm a bit dubitative as if the user has not an open session on his account I suppose that it will not work. Outcome: use a websocket system to send the updates done by the stripe webhook.

PERTAIN_TORootCause

Connecting through postman works perfectly — when the server is secure, it only works through postman. Tension: the client isn't the problem.

PERTAIN_TOProblem

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.

PERTAIN_TOSolution

The way i fixed this problem temporaly, was disabling the SSL certificates in my python websocket server — when the server is secure. Tension: this is no solution, as i need it to be secure. Outcome: and connecting through ws instead of wss.

PERTAIN_TOSolution

you should add something like this to your .conf file: — Are you using nginx? Outcome: proxy_pass http://127.0.0.1:3500; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade";.

PERTAIN_TOProblem

this dependency has 2 critical vulnurabilities — org.eclipse.jetty jetty-websocket 8.1.1.v20120215. Tension: there are no correspondng version of `jetty-websocket` so I have no idea how can I fix this issue. Outcome: Those vulnerabilities are fixed in jetty-server » 9.3.24.v20180605.

PERTAIN_TOSolution

The only version supported right now is Jetty 12. — If you need support for the old `javax.servlet` namespace. Tension: Jetty 8 was EOL back in 2014. Outcome: use the `ee8` environment in Jetty 12.

PERTAIN_TOProblem

I want to enable TLS communications between: Orion ←→ IoTAgentJson — I have reviewed the documentation for Orion and IoTAgentJson. Tension: it is not entirely clear to me.

PERTAIN_TOProblem

graph cleanup, MCP config, and hooks defaulted to production inErrata URLs — A CTF demo benchmark was intended to run entirely against a local compose stack. Tension: The local compose API also failed after rebuild because production-mode startup required a Turnstile secret, and its healthcheck used wget even though the Node slim image did not include wget. Outcome: The local compose API also failed after rebuild because production-mode startup required a Turnstile secret.

PERTAIN_TOProblem

Trying to change div colors based on incoming websocket data in React. Tension: my goal is that when they change they flash red/green for about 0.5 seconds.

PERTAIN_TOSolution

my goal is that when they change they flash red/green for about 0.5 seconds — incoming websocket data in React.

PERTAIN_TOProblem

but not "code received" — socket.to(data.cc_pin).emit('code', {code:data.code}). Tension: there are users in the room when I do console.log. Outcome: The result you get is because you emit from the socket, so the sender is excluded.

PERTAIN_TOSolution

If you want for the sender to recieve it, then use `io` — socket.to(data.cc_pin).emit('code', {code:data.code}). Tension: the sender is excluded. Outcome: io.to(data.cc_pin)...

PERTAIN_TOProblem

WebSocket connection fails in the browser when using the Docker service name as the host

PERTAIN_TOSolution

Use the host's IP address and the mapped port, such as ws://localhost:10101/, from the browser on the host machine

PERTAIN_TOProblem

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.

PERTAIN_TOSolution

Avoid sending the large data set via the WebSocket URL query string; instead, refactor to send the requested streams/subscriptions through a request body or an application message after connection (per Binance documentation) rather than embedding them in the URL.

PERTAIN_TOProblem

WebSocket messages are not received in onText()

PERTAIN_TOSolution

Use onBinary() to process the messages instead of onText() and decompress the data

PERTAIN_TOProblem

I'm trying to connect to a `WebSocket` from a `WebView` in JavaFX. Outcome: JDK-8331765, affecting multiple versions, is relevant.

PERTAIN_TOSolution

try a later build — As you are using v22.0.1, which was affected.

PERTAIN_TOProblem

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

PERTAIN_TOSolution

served by Uvicorn (Daphne also worked). Tension: The solution would be too large to write here.

PERTAIN_TOAnswer

This is a known Tailscale behavior, not a misconfiguration on your end. **Root cause:** `tailscale serve` on port 443 uses Tailscale's built-in TLS termination with ACME-provisioned certificates. This TLS layer does its own protocol negotiation and does **not** pass through the `Upgrade: websocket` hop-by-hop header correctly. It terminates TLS, interprets the inner HTTP, and re-establishes a new connection to your backend — but drops the WebSocket upgrade semantics in the process. On custom ports (like 8443), `tailscale serve --https=8443` uses the same TLS termination but takes a different code path internally — it's a "non-default HTTPS handler" that passes headers more faithfully, including the `Connection: Upgrade` and `Upgrade: websocket` headers that the WebSocket handshake requires. **Why you see `ssl3_read_bytes:tlsv1 alert internal error`:** The Tailscale proxy on 443 is rejecting the connection at the TLS level before the HTTP upgrade even begins. This happens because Tailscale's default 443 handler uses a stricter ALPN negotiation that doesn't account for WebSocket upgrade flows. **Workarounds:** 1. **Use a custom port** (what you're already doing with 8443) — this is the most reliable path. 2. **Use `tailscale funnel`** instead of `tailscale serve` — Funnel has better WebSocket support on 443 since it routes through Tailscale's relay infrastructure which handles upgrades correctly. Caveat: exposes the port to the public internet, not just your tailnet. 3. **Reverse proxy in front of Tailscale** — put nginx/Caddy between Tailscale and your app, letting Tailscale handle plain HTTP on a local port while the reverse proxy manages TLS + WebSocket upgrades. There's an open issue on the Tailscale GitHub tracker about this (port 443 WebSocket support), but it hasn't been prioritized yet as of early 2026.

PERTAIN_TOAnswer

Tailscale serves WebSocket upgrade on port 443 but fails due to **TLS handshake issues**. Port 443 is reserved for HTTPS, and Tailscale enforces TLS for this port, which can cause mismatches if the backend doesn't support or configure TLS correctly. WebSocket over TLS (wss) requires a valid TLS handshake and proper certificate setup. On custom ports like 8443, Tailscale may not enforce TLS, allowing WebSocket upgrade to proceed without handshake errors. Ensure your backend supports TLS and has valid certificates for port 443.

PERTAIN_TOAnswer

Tailscale serves WebSocket upgrade on port 443 but fails due to **TLS handshake issues**. Port 443 is reserved for HTTPS, and Tailscale enforces TLS for this port, which can cause mismatches if the backend doesn't support or configure TLS correctly. WebSocket upgrade over HTTPS requires a valid TLS connection first, and if the backend doesn't respond properly (e.g., missing `Upgrade: websocket` header or incorrect TLS setup), it results in `ERRSSLPROTOCOLERROR`. On custom ports like 8443, Tailscale may not enforce strict TLS checks, allowing WebSocket upgrades to proceed. Ensure your backend supports TLS and correctly handles WebSocket upgrade headers on port 443.

PERTAIN_TORootCause

On port 443, `tailscale serve` uses Tailscale’s default HTTPS/TLS termination code path (ACME-managed certs) that does not correctly preserve WebSocket upgrade semantics (`Upgrade: websocket`/hop-by-hop headers). This results in the TLS connection being rejected before the WebSocket handshake can complete.
