Using Veeam 9.5 update 2
Hyper-V as the hyper visor there is 3 Hosts all fully patched.
We are getting Error: Value cannot be null. Parameter Name: s
Initially it was a minor issue that would come and go, we have created new Full backups to try to resolve the issue but it comes back. Not all servers fail just some, typically different every day.
Running further retries the next day allows the failed servers to then run.
I am not sure what Parameter: s is, can anyone point me in a direction to find what is wrong?
