This happened all of a sudden. I first noticed when packages wouldn't load in Visual Studio's NuGet Package Manager.
Upon further investigation (and, ironically, due to it) I've noticed a lot of sites are refusing to connect. Examples being:
Doing an nslookup
I get this result:
nslookup developercommunity.visualstudio.com

Disabling anti-virus and firewall doesn't help.
After doing an in-place Windows 10 install, the issue was fixed for 5 days. The sites stopped working again today, and upon trying the in-place install again, nothing happened. Only difference was that last time the install caused an update as I was on 1903.
Using a VPN fixes the problem. However, it is not my ISP blocking the sites as they work fine on other devices even without a VPN.
