Setting up my IMAP email accounts in Thunderbird 68.11.0 (32-bit) in Windows 10, get the following error message: ''"Thunderbird failed to find the settings for your email account." '' I have web hosting server account at Contabo. Also added from same server 8 more email accounts to my Thunderbird, all works fine. Except this one. Used the recommended setting Email configuration settings for “mail@gardenservice.ca”. sent by cPanel. 1). I`ve tried to add manually, in offline mode,and after adding the account: still can`t connect. The green process line blinking in the Thunderbird on the bottom right, but after few minutes stopped without any error message. 2.) Also tried to delete the .msf files and folders in Thunderbird profiles folder. 3.) Created a completely new email accounts in cPanel (for this domain, other works fine.), after adding: the same error. 4.)SSL certificate for domain: OK. :mail.gardenservice.ca AutoSSL Domain Validated Expires on October 3, 2020. 5.)Without SSL,port 143,: no luck. Checking the error console showing the following interesting error: "mail.setup WARN Hostname is empty or contains forbidden characters. Only letters, numbers, - and . are allowed" But why? I filled all the settings correctly, no space after the user name or domain...I have no more idea what to do.Thanks in advance!
