Received EOF for non-existent channel #1214

Open moffitj opened 2 years ago

moffitj commented 2 years ago

Using SSH to linux servers works fine.

Connections from windterm to any Cisco device fail with "Received SSH_MSG_DISCONNECT: 2:Received EOF for non-existent channel 0."

Connections to Linux servers from windterm work fine.

Connections from other linux servers to cisco devices work fine.

I am using the windows version of 2.5.0.

The linux (ubuntu 22.04) version of 2.5.0 does not have this problem.
