edge-simplified-92 test is failing due to instance unreachable msg: 'Failed to connect to the host via ssh: ssh: connect to host 192.168.100.50 port 22: Connection refused'.
This failure occurs during playbook task [install sanely failing health check unit to test red boot status behavior]

Following job logs show the failure in different VMs. The first fails with diun_pub_key_insecure enabled and the second one with with diun_pub_key_hash enabled:

On the other hand, I was not able to reproduce this test locally in rhos-01 (test result was successful).

One possible workaround could be to increase the number of retries of the playbook's task https://github.com/virt-s1/rhel-edge/blob/main/check-ostree.yaml#L956
