Starting yesterday (maybe Saturday) we have been unable to initiate any Zoom calls.  They just sit "connecting".  According to Zoom, there are no issues that would lead to this. My investigation, traces I have run on the server, and using a VPN (on a tablet on my LAN) show the exact same symptoms I had a year (or so) ago with a couple of AT&T sites, which I eventually narrowed down to being caused by the same blacklist by routinely switching IPs and then eventually shutting down my relay temporarily. Is anyone else seeing similar and/or have any suggestions as I rather not have to shut my relay down.  Running a multitude of VPNs on my internal machines is not really an option and my relay isn't going to function if I throw a VPN on my server. Cheers.
