Agent not shown as connected on server interface


Hello all,

We have 16 agents currently installed and 15 of them are running well.

I can’t understand why one of them is never shown as connected. I’ve verified network connection but all is ok.

I’ve enabled debug log on agent, and I have these lines :

2018-07-09 10:29:19: SQLite: recovered 24 frames from WAL file /usr/local/var/urbackup/backup_client.db-wal code: 283
2018-07-09 10:29:19: urbackupserver: Server started up successfully!
2018-07-09 10:29:19: Started UrBackupClient Backend…

2018-07-09 10:29:21: Trying to connect to internet server “” at port 55415
2018-07-09 10:29:21: Successfully connected.

So why this agent isn’t running well ?

Thanks a lot



First, make sure you can connect to the server web interface from the problem client:
The UrBackup client connects to the server on Port: 55415 for the backups.
Check your firewall to make sure it includes traffic for 55415 as well as 55414


Thanks for your reply.

Yes firewall is open and telnet confirms that ports are accessible.

Agent’s debug log says that connection to the server is successfully established.

That’s why I don’t understand why this specific agent are not working…
