Hello, I can not connect my two accounts to the E-Mail-Server using Thunderbird. It worked until yesterday. It is still possible on the mobile Phone and also by using the browser directly. It seems to be a Thunderbird-Problem so far. The settings are ok, the worked fine for years and are not changed. I use bananatag for one account. Maybe it is connected to this? Thunderbird version 68.2.2. on a mac. Thank You for Your support in advance.

After installing my Accounts on Mail (Mac), Thunderbird works again without errors. I don´t know, why the error occurred. Thanks for the answer and have a nice day.

That sounds like a server error, have you approached your mail provider?

They told me to contact Thunderbird, because it works from mobile phone and from the browser.
