Resolve "protocol version mismatch" error when launching new terminal on SSH based environment
0
I have created a new SSH based Environment with a inf2.xlarge based instance and am having problems when creating a new terminal window as it is giving me the following repeated error message:
protocol version mismatch (client 8, server 7)
Do I need to update my SSH server on the instance ? The current version of SSH on the EC2 instance is the following:
OpenSSH_7.4p1, OpenSSL 1.0.2k-fips 26 Jan 2017

It seems to be a tmux issue. I resolved it by killing all the tmux sessions with the following command: sudo killall -9 tmux
