Failed to connect to the server (Minecraft)

Hello.I had one problem and I cannot resolve it.When I want to connect to friends,then writes this error (see screenshot).



I do not understand how to solve this problem.I have searched online,on different forums and this error at all.Playing with Tlauncher,other friends can easily connect and I cannot.Tested Hamachi - all works and lights up green without triangles,reinstalled it,reinstalled Java,reinstalled the launcher,turn off the antivirus firewall and installed everything else when they were off.Nothing helps.Help,who can help.Don't actually know what to do!
