Whenever I try to log into a server this pops up.

Note, I did blackout some letters.
ButterSquid, you're good with this stuff right?

 

I'm actually having the same issue, but only for .org.

 

I was playing on my friends server, restarted it, and then anytime I log into a server. This. D:

 

I've been having issues with .org ever since I installed the new version of nodus

 

I use just plain minecraft, so it is something wrong with minecraft I guess...

Minecraft Services Status · Is Minecraft Down? is VERY reliable and trusted.

 

Im guessing you solved it already, but just so you know:

IOException means input output error and I think 503 is a "request denied" code.
