What is the issue you’re encountering

Running out of ideas on what could be possibly causing this. 502 error, only on homepage, only in Chrome, but not in incognito Chrome, but deleting cookies does not solve it. Also, in Chrome on phones no error.

What steps have you taken to resolve the issue?

  • disabling chrome plugins (no change)
  • clearing cache/browsing data (no change)
  • updating browser to latest version (no change)
  • checking DNS (no issue found)
  • disabling cache “development mode” (no change)
  • loosening security rules, disabling browser integrity check (no change)
  • tightening security rules because at this point i am just trying things at random (no change)

What are the steps to reproduce the issue?

go to the homepage and be me or one one of my coworkers. not sure if replicable in general.

Screenshot of the error

To add: logging in from a different google profile also removes the error (but disabling all extensions and clearing all browser data in the original google profile won’t help)
