Internet Can't Download/Browse from Various Websites without VPN

Hello Tech Support Community,

I recently moved to Denver, Colorado and got a new computer. While installing major apps such as VLC, Discord, and WinZip, I notice the downloads are pretty slow and can get hanged up. When opening Discord it will get hanged up on updates. I waited 3 days hoping it was an external issue, but issues remained.

Luckily I remember I have a VPN and installed it as soon as I connected to a Denver, CO VPN Discord updated and opened up. Also various websites I browse suddenly loaded. I was wondering does anyone know what the issue is? Is this with my ISP or DNS service? I'm quite confused. With/Without VPN my internet is 400MB/s.

Thanks for any help!
