Something went wrong

An unexpected error occurred.

UNKNOWN_ERROR

Symptoms

  • The failure does not match any of the specific cases.
  • It may happen only with one particular build.

Likely causes

  • A fault we have not classified yet.
  • An unusual ELF layout that fails in a way the parser does not report specifically.
  • A browser extension interfering with the request.

How to fix it

  1. Retry, then try a second build

    If a different ELF from the same project succeeds, the problem is that specific file. If nothing works, it is the environment.

  2. Try another browser

    A clean browser without extensions rules out interference in one step and takes less time than disabling extensions one by one.

  3. Report it with the error code

    Send the code shown on the error card together with your toolchain and the approximate ELF size — that is enough to reproduce it in most cases.
