Problems connecting to certain sites after previous disruption

Hi, I've been having this issue fairly often on my Windows 10 (20H2) computer. If I am loading a website/service and the internet connection somehow goes out in the process (internet going down, or my VPN disconnecting), the page/service will refuse to load until around 4 hours or longer after the incident.
Before that period elapses, clearing the DNS, manually setting a different DNS server and restarting the router doesn't help. I've also tried restarting the computer but it doesn't work either. Trying to reach the same page using another device works. Any idea what causes this strange issue? Chrome tells me it's some DNS probe error but clearly every other site works.

Had similar issue after 20H2 update and reverted back to image right before 20H2 and guess what NO connectivity issues. Can go to google (which I couldn't with 20H2) and my VPN works. I am running Win10 Enterprise so that "could" be an issue but otherwise sticking with 2004 build 19041.572 until additional updates or bugs are squashed for 20H2. With 20H2 was also receiving several err_connection and DNS issues with sites, cleared cache, resets and nothing corrected it.

Interesting. Well I didn't have the same issue after that post, but I did only notice it happening recently, so perhaps it was the 20H2 update. I thought I was one of the lucky few that never had issues with Windows updates but apparently not.
