Azure Hosting Misconfiguration

azure-runtime-misconfiguration

Azure-specific runtime and access settings (startup routing, CORS preflight vs POST handling, and storage/identity configuration) get mismatched with the app’s expectations, producing 404/500 errors or blocked connectivity with no clear remediation path.

MATCHESSolution

I just switched from npm to pnpm — Azure App Service. Tension: app services tries to run npm install.

MATCHESSolution

Set origin to process.env.CLIENT_URL or http://localhost:3000 in corsOptions

MATCHESSolution

Choose very strong username/password — securely connect my Vercel app to Azure SQL Database. Tension: it does not mitigate the problem.

MATCHESSolution

Move parts of your code to Azure — code that talks to Azure resources in Azure. Tension: then expose that functionality through some API. Outcome: that you will consume through your NextJS app code running in Vercel.

MATCHESSolution

Host your NextJS app in Azure Static WebApp — hosting NextJS app there. Tension: the developer experience of hosting NextJS app there is extremely poor. Outcome: the last time I tried, it just did not work.

MATCHESSolution

In next.config.js. Outcome: allowedOrigins: [ 'localhost:3000', // localhost 'foobar-3000.app.github.dev', // Codespaces ].

MATCHESSolution

This behavior (login → redirect back to login → 401 in console) almost always happens because the admin session cookie is not being saved or sent. — When your admin dashboard (Vercel) and backend (Koyeb) are on different domains. Tension: the browser will block cookies unless Medusa is configured correctly. Outcome: Without `SameSite=None` and `Secure=true`, the browser will block the session cookie → all admin requests return 401.

MATCHESSolution

And HTTP Client errors (if you're using `HttpClient` or `HttpClientFactory`) — On ASP.NET Core. Tension: you just need to opt-in. Outcome: options.CaptureFailedRequests = true;.

MATCHESSolution

Azure App Service. Outcome: and then it worked.

MATCHESSolution

I have enabled CORS. — deployed to Azure web app. Tension: we can't see it being recieved on the frontend. Outcome: Upgrade your app service plan which can handle computation.

MATCHESSolution

Update the frontend to call the API over HTTPS (https://my-api.azurewebsites.net/v1/user/{user_id}). Additionally, configure the Azure Web App to redirect HTTP traffic to HTTPS so insecure requests are automatically upgraded.

MATCHESSolution

Also increase the timeout value for the client. — Deploy the application to Azure again through a different way (VSCode or Azure CLI). Tension: check the logs of the Azure App Service for the complete error details. Outcome: Deploy the application to Azure again through a different way (VSCode or Azure CLI) and check the logs of the Azure App Service for the complete error details.

MATCHESSolution

the deployment fails silently when my code includes azure-identity — deploy a Python Azure Function using GitHub Actions. Tension: The function works perfectly when deployed through VS Code, but not through GitHub Actions. Outcome: replacing the `Azure/functions-action@v1` task with a pwsh task below.

MATCHESSolution

splitting the 12 apps that are on the original ASP and moving half under the new ASP — We are running 12 rather small Azure Function on the Flexible Premium Function service plan. Tension: I do not see us purchasing an additional ASP only to fix this issue. Outcome: we will be implementing our own health-check routine instead.

MATCHESSolution

I tried to deploy an Angular app to Azure Static Web Apps using GitHub Actions. Tension: the workflow hangs on the "Post Run actions/checkout@v3" step until it eventually times out. Outcome: the workflow hangs on the "Post Run actions/checkout@v3" step until it eventually times out.

MATCHESSolution

Set the settings manually in Azure App Service, or use a deployment action to set them via API

MATCHESSolution

Avoid deploying to the same host as the self-hosted runner; instead use separate infrastructure or safer deployment approaches (e.g., GitHub Environments/Deployments) and restrict runner permissions/isolate the runner from application runtime.

MATCHESSolution

You may want to consider configuring your S3 bucket's CORS configuration — to allow specific websites served from other domains to pull your image and display it. Tension: You are serving a mix of HTTP and HTTPS content which often results to this problem. Outcome: hosting the image on a local server that runs on top of HTTP to make sure that all content is hosted on HTTP.

MATCHESSolution

callbacks: { — AzureADProvider({. Outcome: session.user.jobTitle = response.data.jobTitle;.

MATCHESSolution

Your Azure AD Connect service should be using a dedicated service account. Tension: This allows them to detect new and unreported/unkown threats because they look for risky/unusual actions rather than simply a "bad" program. Outcome: allow this specific module import from a trusted user or host.

MATCHESSolution

In Dedicated App Service Plan. Outcome: Use `AzureWebJobsStorage__blobServiceUri` if you are using the URL of the storage account.

MATCHESSolution

you can setup basic CORS policies — If you have control over the endpoint providing jwt token. Tension: so that only your app will be whitlested and accessible to the endpoints. Outcome: Here is the sample example for CORS settings.

MATCHESSolution

Place the WebApp behind a network layer such as Azure Application Gateway or Front Door, which terminates HTTPS and prevents port 80 exposure to the internet.

MATCHESSolution

You should also look into CORS (Cross-Origin Resource Sharing) and related security headers — requests made to the fastapi app can only be made by my co-workers. Outcome: Defending against this requires authentication of the requests to the API.

MATCHESSolution

Use a newer runtime base image such as mcr.microsoft.com/dotnet/aspnet:6.0-alpine for the final stage

MATCHESSolution

HttpClient.GetAsync(new Uri(TextHelper.RedirectUrlNull(urlContent))); — We have an issue in our solution (we are using .net core). Tension: the SNYK vulnerabilities scaner show us that we have a Server-Side Request Forgery (SSRF) vulnerability.

MATCHESSolution

How to specify my environment variable — Azure Portal -> Configuration-> Appplication Settings. Tension: Should it look like - Name: `ecoopt_http_auth-header-apikey` and value: `mySecretKey`. Outcome: Navigate to your App Service in Azure portal. Go to Settings in the left pane and select Configuration. Click on application settings and create it by giving proper Name and Value as key-value pair and save it.

MATCHESSolution

Set msalConfig.auth.redirectUri to the exact Reply URL registered in Azure AD/Entra and use the preferred localhost form (e.g., http://127.0.0.1:5173/home instead of http://localhost:5173/home). Re-run the login flow so the redirect callback completes and tokens are generated.

MATCHESSolution

Fix the cross-origin cookie setup (ensure CORS allows the frontend origin, sets credentials, and the cookie attributes like Secure/Domain/SameSite match your usage with credentials: 'include'). Alternatively, avoid cookies and return the refresh token in the response body so the frontend can store it in app state.

MATCHESSolution

Current workaround is to change your app service to use http 1.1. — Azure app service monitoring tools are limited. Tension: The App Service product team are currently investigating the problem. Outcome: Current workaround is to change your app service to use http 1.1.
