sftp not starting after server reboot

[sponch]

After a server reboot I cant get SFTPGo to start. Logs show:
ERR error initializing data provider: failed to connect to user=usercdd5780385b84f3482b83f6a184xxxxx database=dbcdd5780385b84f3482b83f6a1xxxxxx: hostname resolving error: lookup postgresql on 127.0.0.53:53: read udp 127.0.0.1:36331->127.0.0.53:53: read: connection refused
May 17 21:57:02 => Healthcheck error: Error: connect EHOSTUNREACH 172.18.17.180:8080

Server reboot, restart SFTPGO don't help

can you run cloudron-support --troubleshoot to get an idea what services are down. But it very much looks like a local DNS resolving issue. Did you make any custom configuration changes to the DNS settings on that server?

Hi and thanks. besides MongoDB ervery service seems okay. Just put the app into recovery mode and back - that helped.
