Remote sync job aborts after a while

[David G.]

Hello,

I have a remote sync job that keeps failing.
I suspect it's because the VPN connection isn't that stable, even though I don't have any problems with that in everyday life...
Is there an option for max_reties or a timeout that can be increased?
I also find it interesting that when two jobs are running, they don't both abort at the same time. There is often more than half an hour between them. I find that strange if it's the VPN.
During the initial backup of over 1TB, I simply ran the job every 5 minutes and ignored all the errors. But now it's very confusing. I actually only want to run the job once a day.

Where can I find the log with the some errors?

Edit
This is in the log of the Pbs from which the backups are taken:
