Error with SSH connection: Failed to connect to the host via ssh: mux_client_request_session

[Carlos Fuentealba]

Hello everybody,

I'm using an AWX (container version) and everything works just fine, except for one specific connection.

One node (client) is running Wind River Linux 5.0.1.41 (ERICSSON modified) and when i try to execute my task, the debug gives me this error:

Using /etc/ansible/ansible.cfg as config file

SSH password:

fatal: [10.176.238.197]: UNREACHABLE! => {"changed": false, "msg": "Failed to connect to the host via ssh: mux_client_request_session: read from master failed: Broken pipe\r\nFailed to connect to new control master\r\n", "unreachable": true}

But when i've connect directly from the container it just works.

root@awx:~# docker exec -it 6dfc6ebd184a bash

[root@awx awx]# ssh cfue...@10.176.238.197
