Help needed

[Sophie]

My friend keeps receiving this error whenever he joins any server.

He has:
-Reinstalled Minecraft
-Updated Java
-Tried using OptiFine

There is nobody else using his internet, nor any other devices. It was fine two days ago. Does anybody know how to resolve the issue? If so, thanks c:

Did you try looking through his firewall (windows firewall with advanced security)? Maybe the windows firewall (if he uses windows, if not then just ignore this message) has blocked minecraft to have internet access. You just need to find the windows firewall and go through all the inbound and make sure whenever it says javaw or just java(tm) Platform SE binary, that all of those are checked. If this doesn't help then I will try and investigate a bit, but as of now I don't know what else it could be. ;)

Did your friend by any chance mess around with the network dns? Also, have you tried running minecraft as administrator?

are you sure that his internet is doing fine
because normally that message shouldn't happen unless it is a bad connection

Maybe he should restart his router?

Oh, btw this is the sort of error that kicks all player momentarily. Annoyingly the server often thinks we are still logged in when we relog and we have to totally close Minecraft and relaunch to get in so that we then have 'fully' left the server. But often also, I get kicked out just myself from the server; that is my client and my own java issue. If it's only happening to one person, it's their client/internet. If it's to all, it's the connection by the server to Mojang (or some other server error occurring). Hope that helps.

He/she should probably reset his/her router. Is it just on CubeCraft or is it on other servers too? If it is, he/she should probably contact her ISP.

He should try to just log out and sign back in. If that does not work, he should either restart his router, or look through his firewall to check if anything is wrong.

Try to reset his internet or use the lastest version of MC
