New backup (beta) stops working

Last week this feature stopped working. Connection to remote backup server is ok, test connection is ok. When backup is initiated manually and automatically folders are correctly created on remote server (if they dont exist), but nothing has not been sent to the remote server.
Tail for cron_backup.log:

Code: [Select]

tail -f /var/log/cwp/cron_backup.log

2021-01-14 20:00:02 END
2021-01-14 20:00:05 UPDATE backups SET LASTEXEC = "2021-01-14 20:00:05", STRUN ="0", BACKUP_FORCE="0" WHERE ID="5"
I tried deleting backup and creating new one, rebooting the server, deleting and creating folders manually on remote server.. Nothing seems to help. What should I do to fix this?
Thank you
