I am having an issue with my NAS SMB Backup Repository that suddenly became unavailable.
If you will look at the screenshot of my Veeam, the two NAS repository is unavailable.

Please also note that I am able to access the NAS in the explorer

There is an error when i try to reconfigure the backup repo

The troubleshooting that I did was to restart the Veeam backup service but that did not work and the backup repo smb is still unavailable.
I also tried to put the backup repo in maintenance mode and remove it and it is still unavailable.
I have the same NAS smb backup repo setup on my other hyper-v and it was just cool and no issues.

Please help me on this issue as it is failing to backup my VMs because of this issue.

I haven't tried restarting the host because there are many services that will be affected and I am hoping that you will be able to help me and will be able to solve it without restarting the server.
