Dear all,

suddenly duplicati stopped working on my Ubuntu Server 20.04. Iam not sure when it stopped but i did not update duplicati or anything significant on the server:

Systemctl shows the following:

ā— duplicati.service - Duplicati web-server
     Loaded: loaded (/etc/systemd/system/duplicati.service; enabled; vendor preset: enabled)
     Active: failed (Result: exit-code) since Mon 2022-04-25 15:51:18 CEST; 55s ago

Rebooting did not help. Also systemctl restart gets the same error.

My installed version is: duplicati_2.0.6.3-1_all.deb

Shows nothing listen on port 8200

Unfortunately i cannot find any logfiles to get more details about the error, any ideas?

Thanks !

I solved the issue. The Server had an ip change recently and the old IP was defined via the DAEMON_OPTS parameter. Changed the IP to the new one and it worked again.
