I'm trying to log in to my repository with the user that has permission to the datastore of my host machine. I'm using:

proxmox-backup-client login --repository user@PBS@ip-vm:datastorename
Which in return gives the error: Error: permission check failed & sometimes gives this error when logging in with root: Error: authentication failed - ticket with bad timestamp: invalid digit found in string
Initially i had an option to give in a password in the beginning but i must have entered a wrong one and now the ticket seems to have saved that invalid password.

On the Backup Client Usage doc page, it states "To remove the ticket, issue a logout", however this does not seem to remove the ticket as i do not get any prompt to enter a password after trying to login again.
