None of the unity learn videos are loading

So none of the videos on the unity learn pages seem to work for me. They just keep buffering forever and never starts up. I can download the video using IDM and it works fine after that but not on the browser.

I have tried googling and figuring out a solution for the past 3 days without success and I am at my wits end now. I have tried everything from clearing cache/cookies, different browser, restarting pc/router.

It works when I open it on my phone on the same wifi, so its not an isp issue. Anyway, kinda just gave up and bought a course on udemy. Just wanted to log this issue so the unity peoples are aware.

I was struggling with the same issue and found a workaround.

The root cause is that AdGuard mistakenly blocks API requests, thinking they are ads or tracking attempts. Once blocked, the issue persists even after disabling AdGuard.

A simple solution is to install a browser extension that allows CORS requests. Just search for “Access-Control-Allow-Origin” in your browser’s extension store, install it, and enable it. This should allow the video to play again. After that, you can disable the extension.

However, if you re-enable AdGuard, the same problem will occur again.
