Feel free to open a new bug for fixing nntp-connection-timeout. I don't know if I can help, other than trying out suggestions and providing feedback. In the meantime I'll keep using my workaround replacement function. But I wonder, could this issue have been triggered by some change in news.gmane.io around early to mid December 2021? Because that's when the problem start for me, and prior to that I don't recall ever having this problem (perhaps sporadically but not with such persistance). Steve Berman
