Firewall: Access Firewall which may be controlled by the OS or by an Anti-Virus program you installed. Thunderbird must be set up as an allowed program.

VPN Please check computer and Anti-Virus product to see if a VPN has been enabled. Server does not like VPN, it will block access. So switch off VPN or create a split tunnelling and set up Thunderbird to use it.

'Localhost' If you use a program that uses 'localhost' - some people manage websites so might use something like Apache Xampp - Switch it off until Oauth has been set up.

I had this problem with both Google and Yahoo. It seems to be related to the OAuth2 system.

The problem for me was the localhost server Xampp was in operation. I deleted the whole of Xammp as I do not need it currently. Once I deleted Xampp, everything worked as expected.

To test if a server is present enter http://localhost or http://127.0.0.1 into a browser and see what is displayed. No server will be present if you get the following message: "This site can’t be reached 127.0.0.1 refused to connect."
