Failed to connect to the server

I can't log into the server whether it's my account or my alt accounts.
I already tried re-installing.
Oh and I can't log into CosmicLeague too. (IDK if that has anything to do with this.)

I don't know much, but judging from the playercount for the past few days, it's probably either a firewall problem or an internet problem (slow internet and such). Maybe try restarting your internet connection? (router or something along those lines)
