The 502 Gateway error was so annoying before I found this article. I corrected my Windows firewall settings to fix the error and now I am able to load the websites.

Refreshed the page 10 times but the gateway error kept sticking to my screen. I even tried restarting my computer and web browser but I could only fix the error when reviewing the DNS settings.
