Cannot connect to my work computer "Authentication Rejected" message.

Since last week I cannot connect to my work PC. Every time I tried I get the "Authentication rejected" message. I already tried the following with the same results:

- Reinstalling Teamviewer on both computers.

- Using another computer to connect to my Work PC.

- Using another internet connection.

- Connecting inside my work network.

What is weird is that I can connect to Mac computers but not to my PC.

Teamviewer version is 11.0.76421

OS: Windows 10
