I redeployed my application (name “colours”) yesterday, and have an odd problem. The health checks are passing (the deploy succeeded), but the application is not accessible. I can SSH into it, and I can see it’s running fine (It’s Elixir so I can connect to the running instance after SSHing in). However I cannot access it at the public address. I can ping the address, but curl hangs.
Re-deploying has no effect (it successfully redeploys, but no change)
Scaling to 0 then back to 1 has no effect (same as re-deploying)
The logs are basically empty - they show the application starting up after deploys, but then show nothing (as requests are not reaching the pod).
It is deployed in LHR, and I know there was some maintenance going on yesterday so I am wondering if it is related?
