Hi,

I have a ssh connection problem with a host when I launch a template.

" “msg”: “Failed to connect to the host via ssh: ssh: Could not resolve hostname xxxxx: Name or service not known\r\n”,

But when I connect from the hosts where it is running awx connect without problems.

I am dns in the machine where de Aex is ok.

Attach logs,

Hi Antonio,

I have a similar problem with servers that are not in DNS. Haven’t found a solution yet, but I’ll let you know when and if I do.

Regards,

Bruno

How did you test DNS functionality from the AWX host?

I would do something like this:

cat /etc/resolv.conf

host dliwebfe02

docker exec -it awx_container /bin/bash

cat /etc/resolv.conf

host dliwebfe02
