Being new to VEEAM, I might be troubleshooting problem that's trivial for VEEAM experts.
On Veeam 12.2 and vCenter 8.0.3, my problem is ESXi hosts having multiple networks which causes Veeam's confusion. There's management network and there's vMotion network. The hosts in vCenter are defined as follows:
The problem is, Veeam isn't able to back up a single VM. The log is full of these errors:

It's worth noting 172.16.0.0/24 is not accessible outside of VMWare (i.e. also unreachable for VEEAM).
How can I make Veeam to connect to 10.250.100.0/24 and not 172.16.0.0/24?
During the vCenter "object" configuration in VEEAM, the connection from VEEAM to vCenter works perfectly (correct credentials, network visibility, ...)
Thanks in advance
