Comment 6 for bug 1874257

Hello,

This is an issue with VPN MTU configuration. May I know the root cause why this is causing the issue? After adjusted the MTU , this is fixed.

As the same time putty works without any modification.

Why ssh client not negotiating properly with the default MTU

It could be a noisy or unreliable connection to the server. Probably that data corruption is happening to the packet when it is sent, which is my assumption

From ubuntu community point of view any suggestions>

thanks
Jay
