   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Thunderbird is permitted to access the web.

The Automatic Account Configuration in release 138.0 (64-bit) is not working for me on my WIN11 laptop. When I try to add my Comcast Email account to Thunderbird it finds the information for Comcast in the Thunderbird ISP Database. But when I continue by selection "done" the Credentials Window opens but fails to connect with this message: ''Unable to connect The connection was refused when attempting to contact localhost. The site could be temporarily unavailable or too busy. Try again in a few moments. If you are unable to load any pages, check your computer’s network connection. If your computer or network is protected by a firewall or proxy, make sure that Thunderbird is permitted to access the web.''' This process works perfectly on my 2 other PCs running Win10 with Thunderbird release 128.10.0ers I would really appreciate and ideas or steps to correct this issue. Thank you
