cloudron hangs up needing a restart at least every few days

[tadeas]

Hi, I've had this problem almost the whole time using cloudron, but it has intensified the last few days and weeks - cloudron "hangs" - I can log in via ssh, but no apps are working, and neither is the my.* cloudron interface. This used to happen a few days inbetween, now almost every other day. Running latest cloudron version.

I have tried backing up, reinstalling ubuntu (I am using contabo vps) and restoring, but the problem is still occuring.

I can provide access to the machine if you want to inspect the logs. I could not find anything special in the cloudron logs myself.

Actually this is not the first time this happens on customers on Contabo. If it happens, does a systemctl restart docker help?

Same here. I'm running cloudron on a contabo vps. Every few days cloudron hangs. To connect again I need to restart the whole vps. Just restarting docker does not work.

When I try to login to nextcloud i get this error:

Interner Serverfehler

Thanks for the hint, this looks like in such a case, the nginx reverse proxy cannot connect to the docker subnetwork, in which the apps are spawned. I wonder if contabo has some custom networking or firewall scripts, which from time to time overwrite the configuration Cloudron expects.

If this happens again, could you attempt to ping the gateway with ping 172.18.0.1?

Also since this appears to be contabo specific, maybe try to contact their support in such a situation as well, possibly they can take a look and give more insights on the case.

I never got such an error in nextcloud and could not figure out the cause from the logs. Restarting docker sent the whole VPS into unreachable state.

Since then I have migrated to Hetzner (a bit less storage space, but fully SSD) and have only booted once there with no more restarts. Contabo is probably also running some heavy optimization to be able to offer the VPSes for such a low price.

@nebulon I can ping the ip 172.18.0.1

ping 172.18.0.1

PING 172.18.0.1 (172.18.0.1) 56(84) bytes of data.

Is there something else I should test?

We have found out that Contabo has many random issues running Cloudron. The conclusion for now is, that we cannot reliably support Contabo as is, maybe the situation gets better with running ubuntu 18.04 there. I will close this thread so far as there is nothing we can currently do really.
