After a server reboot, the client started to report Error during server authentication and backups are failing
Already deleted the /usr/local/var/urbackup/server_idents.txt and recreated it restarting the urbackup client services. Client worked for some seconds and came back reporting Error during server authentication
Client’s UrBackup is reporting the following error: Oct 09 22:27:12 panthro urbackupclientbackend[156549]: ERROR: Client requires encryption which server does not offer
Compare client’s password on both sides. In my case, after recent upgrades they simply don’t match for auto generated Windows installation files - some dodgy characters are appended at the end of password string.
Just to be clear - I was talking about older version (looks like this issue was resolved) and Windows clients in internet mode, in which case server side on the client’s settings page, client side settings via the tray icon.
But now I see that you have a completely different setup.
