I'm sorry to hear about the issues you're facing with your VMware vSphere environment. It does sound like certificate-related problems could be causing your login issues and backup failures. Let's try to troubleshoot this:
Check Certificate Expiry: It's essential to ensure that the SSL certificates in your vCenter Server are not expired. Since the commands you've mentioned don't seem to be working, you might want to try using the VMware Certificate Manager utility (certificate-manager). This utility allows you to review and update certificates.

From there, you can navigate the menu to view and manage certificates.
Verify vCenter Services: Make sure that all vCenter services are running correctly. If any service has failed to start, this could be contributing to your login issues.
Check vCenter Server Logs: Review the logs in /var/log/vmware/vpxd/ on your vCenter Server Appliance. Look for any error messages or warnings that might provide more information about the issue.
Veeam Configuration: Regarding Veeam, ensure that the Veeam server can reach the vCenter Server and ESXi hosts. Check the Veeam configuration and make sure the credentials are correct. Also, verify that the Veeam services are running without issues.
Backup and Snapshot Removal: In case your backup issues are related to snapshots, you may need to remove or consolidate snapshots for your virtual machines if they were left in an inconsistent state after the incident. Be cautious when doing this, as it can affect VM performance. Projectors Focus
