Bug to play in minecraft full 1.8 multiplayer

Hi, I've a bug with minecraft 1.8... I've tried to connect on a 1.8 server but it doesn't work. It's the same for all 1.8 minecraft server. I don't think it's my java because I already tested with java 7 and java 8. When I try to connect on a 1.8 server, I've this error message: Internal Exeption: io.netty.handler.timeout.ReadTimeoutExeption while the server is opened. I don't understand what's going on. I don't think it's my firewall. I haven't this bug in 1.7 . I tried to fix the bug by setting the command prompt 'netsh winsock reset' but it doesn't work for me.

Can you help me please ?

Best regards,
