My apologies, I guess I did do a bit of troubleshooting with different browsers from multiple machines but forgot to mention it.
- I’ve tried in both Firefox and Edge on both the local machine and from another machine on the network.
- I lowered my tracking prevention settings from strict to standard and still no change.
- Disabled uBlock Origin and Privacy Badger extensions on Firefox with no change. No extensions are installed on Edge.
- Cleared the cache in Edge with no difference made.
EDIT: I have it sorted out now. This thread that was posted today for the same issue sent me down a rabbit hole.
Repairing the installation with the msi after killing all AMP processes, rebooting, running “ampinstmgr upgradeall” from a command prompt running as an admin, and finally rebooting once again got it going again.
My original upgrade must have broken in the process.
