Unable to open any local AccountRight files today

I'm attempting to open a local file, AccountRight v2026.3, Admin user with no password, error message advised incorrect password.

My colleague also failed to log in to a local file, same version, error msg: unable to automatically confirm your file.

A client's attempt also failed, same version, was prompted to confirm the file with zero days remaining. They are on a live chat session now. 

Any advice on what's going on?
