OC install logs

Description of problem:
Overcloud deploy fails on hybrid environment because nodes are unreachable. See 
logs attached:
fatal: [computesriov-0]: UNREACHABLE! => {
    "changed": false,
    "msg": "Data could not be sent to remote host \\"192.168.25.16\\". Make sure this host can be reached over ssh: OpenSSH_8.0p1, OpenSSL 1.1.1c FIPS  28 May 2019

However, nodes are reachable, both virtualized controllers or BM server computes:

Workaround:
Right after the overcloud_deploy.sh script fails with this error, the script (or the infrared OC install command) is reexecuted and it passes.
But this is not valid for QE automated jobs.


Version-Release number of selected component (if applicable):
RHOS-16.1-RHEL-8-20200424.n.0
openstack-tripleo-common-11.3.3-0.20200423204446.86569f2.el8ost.noarch

How reproducible:
2/2

Steps to Reproduce:
1. Install OSP16.1 with infrared/CI job
2.
3.

Actual results:
OC deploy stage fails

Expected results:
OC deploy stage succeds
