Failed To Connect To The Server.

Hi.
I wanted to play on this server, but from the very beginning i have some problem.
Anytime i try to join this server i get this message:
Failed to connect to the server
Failed to login: Invalid session (Try restarting your game)


I tried to restart minecraft, but that didn't help, so I waited couple days because maybe this was some server problems, but this is still happening. I tried to play also on multiple minecraft versions such as 1.11.2, 1.8.9 and 1.8.
I don't have many ideas what cause it may be, so I'll be glad for your help. Thanks in advance.

 

Not sure if this will work but try putting .net .org or .com in the server IP sometimes that fixes some issues.

 

No, it is not helping... I was trying it on minecraft 1.8, so I don't know if that makes any difference. Also I'm using TLauncher to play minecraft. It also may be the cause.

 

Close your launcher entirely then open the launcher again and start mc. After that it should work again.

 

I know it should help, but it doesn't. I tried doing that closing normally and through task manager and it isn't helping at all. Also i am having this problem since 3 or 4 days.

 

try using the default launcher

 

This happen when you connect to another server before this one.
It's a bug that happen on every servers.
Are you sure you don't connect on anything else ?

 

With using default launcher it may be a bit hard because as far as I know you have to have minecraft bought, and I haven't bought it. I may be wrong.

Well, I don't have any other servers so I don't think it will be that...

 

You have to have a premium account to play

 

Oh... That explains that I wasn't able to play on this server.
Thanks for your help. Topic to be closed.
