Upgrade from 2.3.4 to 2.4.1 killed proxy abilities
Earlier this week, I upgraded 2.3.4-RELEASE-p1 (amd64) (running as a VM on Esxi 6.5) via the online upgrade to 2.4 and then to 2.4.1. Just prior to doing it, I made a snapshot.
It seemed to go ok but after the final upgrade, I was not longer able to go to about 75% of websites from a browser (both Firefox and Chrome). I'd get a message saying something like "site not responding".
I immediately restored the snapshot and all is well.
