Trouble Deauthorizing Computers

I’m trying to deauthorize my account on two computers and have been getting two separate errors that prevent me from doing that. On my Mac, it asks me to log in when i try to deauthorize every time and my PC tries to contact the server then says “Could not deauthorize application. Please try again.” Obviously when I try again, I get the same message.

If someone could deauthorize these computers for me or suggest a fix to this issue, that would be great!

Thanks
