  Hi @Ricavir

  If you are getting a 500 response, there must be a detailed error log on server side. Could you check the logs and share related error message ?

  Hi @Ismcagdas,

  No we don't have any error message logged in server side. This seems to be linked with Chrome browsers. The same exact request sent with edge or Firefox is working fine. Here is the message displayed :

  It is not something we can reproduce easily, it only happens for some users. We noticed only on Chrome with Windows 11.

  In Kudu detailed logs, I found this :

  

  Any idea ?

  We really have to fix this as it is impacting several users right now. Tks

  @ismcagdas, I have more information, the error reported on server side is :

  StatusCode cannot be set because the response has already started

  here are the server logs :

  The problem is occuring in the startup.cs file, here is the code line :

  app.Use(async (context, next) => { await next(); if (context.Response.StatusCode == 404 && !Path.HasExtension(context.Request.Path.Value)) { context.Request.Path = "/index.html"; await next(); } });

  Only POST requests are firing this exception ; If the user waits for 5/10 min, the problem disappears. Seems to be linked with JwtTokenMiddleware... maybe with a worker in charge of jwt tokens
