I need step by step setting up Protonmail to Thunderbird. I had this set up before but it stopped working. I know my emails and their corresponding passwords are good because I have access on the web. I am getting "unable to log in at server. Probably wrong configuration, username or password" When I try to put my newest address in. Not only do I know that my passwords for my emails are correct, but I also have a copy of the screenshot of the configurations from when I set it up before: Imap, hostname, port, username, password security. I use this to double check when I go into the Manual configuration account setup. The other error I get is "login to server 127.0.0.1 with username Grammy14@proton.me failed." This email had been working just fine until April 19. I love Thunderbird's set up when it works, and I donate regularly. I have been working on this for a week now. It would be great to get live help. I would gladly pay for the help. It would be nice have that option.
