apt-get update / Domain resolution issue on Ubuntu 20.04 in Chromium / Firefox browsers

[xyzib]

When you type in a domain to the URL bar in the format: xxx.com, it doesn't resolve / times out while trying to load, however https://xxx.com (clicking a link to https://xxx.com also resolves immediately.

Connected to IP address: 172.104.16.201 in the USA.

Additionally, the apt-get update command seems to not be working while connected to the VPN.

Could possibly have to do with this piece of networking functionality on the browser side:

apt-get could be using different ports / a different kind of traffic that's unsupported.

On www-client/firefox-81.0.1 it defaults to http with foo.org but the prediction thing switches to https and adds a trailing slash if it recognizes/remembers the domain. From the browser side, the "fix" is basically using a plugin, eg, https-everywhere
