The authentication servers are currently not reachable

I have a problem with connecting to the servers, whether they are servers with my friends or big servers like hypixel. Whenever I try to do that I have this pop up (attached to the post). I don't really know what to do. I have reseted my router, laptop, reinstalled minecraft, updated java, did things this guy did in this video from youtube: https://youtu.be/DAEkA2LEyb8 , tried connecting from a hotspot created by my phone. Nothing really works! What can I do? I bought premium just yesterday and I can't do anything with it! English is not my first language, hence all possible mistakes.
