2 Factor Approval Not Working from NextCloud Windows App

Hello,

I’m running NextCloud with 2FA via NextCloud notification. It was working fine from my phone, but my phone app was logged out and it’s not working from the windows nextcloud app. I get the notification, but clicking approve doesn’t do anything. Never logs in. I didn’t have a functioning backup option for 2FA, so I’m now locked out (except for windows sync app which is still connected).

Is there anything I can do to restore my access? I still have access to the linux server, just not the nextcloud frontend.

Please help.

Thanks.
