Description of my issue

Since today I noticed the entire YunoHost service (webadmin and all my apps) stop working after some minutes. I can’t access their websites, it’s says time out. Accessing through the direct IP in HTTP shows the default Nginx page. If I restart the VPS, everything goes back to normal, but stops after some minutes.

The VPS is still working fine, plenty of RAM available. I tried restarting YunoHost services, from its own command and systemctl. Didn’t sent any logs since I don’t know what to send, since the webadmin is down.

Thanks in advance

I was able to find this error log when trying to reload yunohost-api service:

Updated info in the first post.
For some reason, since I changed my DuckDNS subdomain to a DynDNS one, the problem didn’t happed anymore. IDK if this can be related.

Hi sapocururu,

Welcome to the forums!

Strange error you got there. It seems the authentication got reset.

I am not familiar with Oracle cloud (and all my limited familiarity with Oracle likes to keep Oracle at a large distance :stuck_out_tongue: ), nor with DuckDNS (even though that seems a much friendlier entity).

Did the issue reoccur since switching to DynDNS?

Yeah, it’s not a great relationship :sweat_smile:

Three days later and it’s still working fine. Seems to be a issue with DuckDNS, for whatever reason I cannot explain.
