Mooohhoooo,
for the last 2 weeks i have had the problem that the container unbound-mailcow restarts regularly. then there are connection problems.
i am running the current release 2024-04 on debian 12.
Example
Couldn’t connect to host, port: 162.55.XXX.XX, 993; timeout 20000 failed to connect to mail.axxxxx.eu/162.55.XXX.XX (port 993) from /100.102.178.78 (port 47184) after 20000ms: isConnected failed: EHOSTUNREACH (No route to host) isConnected failed: EHOSTUNREACH (No route to host)
curl: (28) Failed to connect to www.internic.net port 443 after 131427 ms: Couldn’t connect to server
The DNS entries are also recognized as incorrect and the server IP is set to “current status”.
after a server-reboot and pull the images it works again for 1 day.
i hope someone can help me
Thanks and BR Andy
