I can't recall when this started happening but it was probably after a Mac OS Big Sur update many moons ago. I'm currently on 11.2.3 (20D91) and latest Parallels version. Basically, I was previously using Bridged Network just fine. I do web development and app development so the Windows VM serves up the web site and services my app connects to. All that was working just fine then it broke. What I noticed was that on the Windows VM I couldn't get to any websites and the ones that I could get to had content errors. When I inspected the network communications via Chrome or Edge "inspect" feature showed a bunch of SSL errors. My antivirus also couldn't download and install updates. When I switched to "Shared Network" I can use my Windows VM as expected other than being able to connect mobile devices to it, so that doesn't seem to be a feasible solution. I appreciate any help anyone can offer.
