Unusable application

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

klawitterb

So decided to upgrade my server to Ubuntu 24 and its working now again.

nebulon

Strange how that would have affected it, but well glad it works

Lanhild

@nebulon I did the upgrade from Ubuntu 22 to 24 today. I confirm that it fixed the issue for me as well.

Lanhild

@nebulon

I have another Cloudron server for which I did the upgrade too. Though, it didn't fix it for this one.

No outstanding errors in cloudron-support's output.

I'm pretty much at a dead-end here

robi

@Lanhild after the server upgrade, did the app upgrade yet?

Lanhild

@robi Yes

Cloudron Container Registry 2.6.0 (registry 3.1.0)

Hello @lanhild
Can you send me a direct message with some credentials (username + app password for the docker registry) and the URL for your docker registry app?
I would like to attempt a push from my side to validate if it is not some obscure local issue.
