This may be related to the 525 errors (Cloudflare 525 error randomly occurs - #3 by greg) if kurt or someone on the team is playing with the proxy but a few moments ago I got a notification of another app failing, different to the one there, this time with 502 errors.
And when I look at the app status, all is well. Has one instance, running in ams. I haven’t touched it for ages, no deploys or changes.
But when I look at the logs, with
flyctl logs, I see pages of errors where it looks like the request arriving in lhr, from me or a healthcheck, is failing:
2021-06-30T00:22:34.487955794Z proxy lhr [error] error.code=1002 error.message="No suitable (healthy) instance found to handle request" request.method="HEAD" request.url="/admin/signin" request.id="01F9D4NTQM2PJX6XF2SW08A786" response.status=502
That’s from a healthcheck test URL which should respond and work. I can’t connect to it either, requests timeout for me in browser too.
Hmm … not good. I can try making two instances as a temporary fix? Or give it a restart? Shouldn’t need to but wondered if you were changing anything currently?
