Observed message

408 Request Timeout

Why it happens

  • The client did not send the full request quickly enough.
  • The network or proxy path interrupted or delayed the request.
  • A large request body took too long to upload.

How to fix it

  1. Retry the request over a stable connection.
  2. Check client-side timeouts, upload behavior, and request streaming logic.
  3. Review proxy or server timeout settings if legitimate requests are timing out too aggressively.
