After that, we got "The remote certificate is invalid" error in backup jobs. Resolved following steps from this thread but still getting SSL/TSL errors in replication jobs.

If your Veeam Server is on Windows 2008R2, apply the following registry value and reboot
Registry path: HKLM SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL
Ensure no jobs are running, restart the Veeam Backup server, and try the jobs again.
This is an old issue with Microsoft where the secure connection caching has unexpected consequences.
