Can anyone help with Bacula?

I have to set up Bacula for a school assigment, just for a PoC basically. I have a server and a client running, and I'm trying to create a backup to a file locally on the server. I could run the default job, backing up files from the server itself, so I think that part is fine. My problem is, I can't create a backup from the client. I can check the status of the client from the director, but when I'm running a job, all the Files and Bytes are 0s.

Can anyone advise with this, please?

Thanks in advance
