Unable to play Multiplayer

Hi, so yesterday i wanted to play multiplayer. I logged on to Multiplayer and all of the servers that i usually can play on says:

"Cant connect to server"

And I've watched so many videos of this problem and it actually seems to be that other people also have this bug/problem.

So how do i fix this?, I've literally tried everything, uninstalled Mc, changed server address, checked my control panel on the java checkbox, uninstalled tlauncher which i thought was the issue but no. So how do you solve this please i need answers?

Felix
