Starting on 11/1/24, Thunderbird won't log into several of my comast.net email accounts. I have about 6 emails set up in TB right now and they have been working OK for literally years. First it asks me to sign in to the Comcast email, and then when I enter my password (I've checked, I am do it correctly, I even changed it, doesn't help). I get the error in the attached file. I deleted the account from Thunderbird, and when I try to add it again, it says it automatically finds the correct configuration, but then I get the comcast login page and again get the same error in the attached file. Again - I have this issue with 2 comcast email ids, but not three others. I have looked at the server settings to the best of my ability and I can't find anything wrong?
