realms / servers do not work

Hiya there, 

 

Firstly, when i try and join servers eg. hypixel, it comes up with an error saying ''failed to log in: The authentication servers are currently down for maintenance. when clearly the servers are not down. My next problem is that i can not load into realms, as it endlessly just loads and doesn't give me an error code or anything. i have tried a lot things to try and fix it and nothing has worked including messing around with my firewall as people suggested and still didn't work. if you guys could help that would be awesome. 

 

Thanks
