Unusable application

[klawitterb]

Log spam seems to be gone now, still having trouble with the actual connection to the registry on my cloudron:

Docker registry resides on the same cloudron

[msbt]

@klawitterb try without https://

[klawitterb]

Without https:// I'm getting: Invalid serverAddress: socket hang up

[msbt]

You got a typo in there maybe, or a firewall?

[nebulon]

So it should work without https:// there so the socket hang up is the issue somehow. Can you telnet via ssh to the registry from that server?

[klawitterb]

Just tried, that just gives me a telnet: Unable to connect to remote host: Connection refused

[nebulon]

If docker.apehost.de is the actual server, then I am able to contact that app from here at least. Does it correctly resolve on the system where it fails?

[klawitterb]

From the server:
ping -n docker.apehost.de -> works
telnet idontexist.apehost.de -> Name or service not known
telnet docker.apehost.de -> connection refused
docker pull docker.apehost.de/path-to-exisiting-image -> Error response from daemon: Get "https://docker.apehost.de/v2/": context deadline exceeded (Client.Timeout exceeded while awaiting headers)

From my local machine:
docker pull docker.apehost.de/path-to-exisiting-image -> works just fine

[nebulon]

So then telnet docker.apehost.de 443 also times out I assume. Is hairpin correctly working for you? run cloudron-support --troubleshoot to see this

[klawitterb]

Indeed seems like hairpin doesn't work, from troubleshoot:
[FAIL] Could not load dashboard domain.
Hairpin NAT is not working. Please check if your router supports it

I just tried the good old have you tried turning it off and on again, interestingly troubleshoot now errors with:
[FAIL] Could not load dashboard website with loopback check
