I experienced several disturbances in the Force yesterday while working the Apple forums. Several times I had total stall-outs/hangs after editing a response I made. Seems better today.
I seriously doubt anything is amiss with your computer or network unless you are running useless anti-virus or so-called "cleaning" apps. Some ad-blockers can wreak havoc with web pages.
Cheap client-side VPNs, the one that spend $millions on TV adverts, are useless and sometimes dangerous. If you need a VPN for working off-site, your IT team will issue you a proper one compatible with their corporate software.
All I can offer is keep trying. The forums are so massive that they practically have their own weather system where things go "boink." The team behind the scenes usually acts fast to quash forum issues that arise, so please hang in there!
