Comment # 2 on bug 1204070 from Zombie Ryushu

I use the eGroupware-docker package. I have removed the plugin to attempt to
use Thunderbird's CardDav and CalDav Sources. The same thing happens.
Thunderbird acts as if its going to connect, hangs there as if it is
processing, and after a while gives up.

TbSync is listed as incompatible with Thunderbird 102. (the version on the
Thunderbird Addon Page says that), but you can side load a beta XPI from github
produced by the author. It doesn't work either. It downloads Zero contacts. 

The version I have of Thunderbird is:
