Hello. Whenever I try to open Youtube while connected to any of my school's internet (guest wifi, student, etc). I am almost certain it is not blocked by the school, because A. other people can open it just fine, and B. it doesn't say that the website is blocked. It seems to just refuse to load.
Youtube attachments in Discord or Reddit also do not load. I use a MacBook Air 11" from 2014, and am on macOS Mojave (10.14.2). Any help is appreciated.
EDIT: I should add that this happened before I got an Adblocker, and don't think that it is related to the issue.
