Check status.janitorai.com first; on October 7, 2026 it showed Backend and Frontend operational with no reports in 7 days.
If the status page is green, test another device, a private window, and Janitor AI's built-in model to isolate the cause.
The same error number means different things: a site 401 is a login problem, a proxy 401 is a wrong API key.
502 is a temporary server-side chat issue per Janitor AI; there is nothing to fix except waiting.
Older proxy guides list retired model names; OpenRouter had no :free DeepSeek model on October 7, 2026.
