Description of problem:

How reproducible:

Always

Is this issue a regression from an earlier version:

No

Steps to Reproduce:

1. Sync RHEL repositories, publish CV, Create AK on Satellite with IPv4

2. Register a host with a workaround from https://issues.redhat.com/browse/SAT-27688

3. Try to run a REX/AnsibleREX job on IPv6 host

Actual behavior:
IPv6 host can't reach to the Satellite with FQDN or IP causing REX/AnsibleREX job to fail with following error,

1:Error initializing command: RuntimeError - Could not establish connection to remote host using any available authentication method, tried publickey
2: 
3:Authentication method 'publickey' failed with:
4:ssh: connect to host 2620:52:0:9f:f816:3eff:fe8d:7871 port 22: Network is unreachable
5:Exit status: EXCEPTION
6:StandardError: Job execution failed 

Expected behavior:

IPv6 host can be reached to IPv4 Satellite directly or with a proxy jump, and REX/AnsibleREX job runs successfully on IPv6 host

Business Impact / Additional info:

foreman-proxy user is able to ssh to IPv6 host using a proxy jump
