Failed to verify TOTP challenge

My TOTP failed suddenly so I removed the tfa.json and tfa.json.lock lock files from /etc/proxmox-backup/ and now I can't verify TOTP. Inside /etc/proxmox-backup/ the tfa.json.lock lock file keeps getting created right after I delete it. Running Backup Server 2.4-1. How can I get TOTP working again?
I've also run a proxmox ve server and have never had this happen, only on my backup server. What do you mean by all devices exactly? The proxmox backup server is standalone.
Note that if enter your tfa code wrong 8 times your user will be locked. As of today, the web ui will tell you that your credetentials are wrong, rather than telling you your user is blocked.

In such a case, if you have ssh access to the server. you can run pveum user tfa unlock USERNAME.
