For over 2 years now I have experienced an issue where trying to visit minecraft.net (and ONLY minecraft.net) to do pretty much anything other than viewing the main website directly using the url (even things such as pressing the Minecraft logo on top of the website to be redirected to the homepage) results in an "Access Denied" error. I'm only now filing a bug-report since I've always been able to bypass this error using Incognito in my browser - this broke today, meaning I no longer can download the game, change my skin/cape etc. The main problem with this issue is the fact it lasts over ISP changes, computer changes, Windows reinstallations etc. and I cannot find the reason for me being instantly blocked from any minecraft.net website. First thing I'd think of would be the extensions, but since the issue also happens in incognito mode (without any extensions), I am out of ideas. Happens on all browsers I've tested so far (chrome/firefox/edge).

A screenshot of the issue is attached below. 

I hope this issue can be resolved quickly, as it is more than annoying for obvious reasons.
