First got the problem on my laptop via. wireless, today I got it on my desktop.
Problem was Firewall Setting on Verizon DSL Westell 7500 modem. It was set to Typical Security (Medium), changed to Minimum Security (Low).

There is a problem here. It's this: Thunderbird doesn't tell you *which* email server has the problem - and so one is left unsure how to fix the problem. Also, in general, this error report window is a mess - see the image here, which shows the window as it appeared at the very bottom of my screen: https://imgur.com/a/Gx4Uf
