Cerberus check fails with SSLEOFError

[svetsa-rh]

Looks like another issue we hit because of http_proxy/https_proxy failure or missing python packages.

Error reported:

This could be related to the bug https://issues.redhat.com/browse/OCPBUGS-2557. The router-perf test prior to the cerberus job broke all routes of the cluster.
I didn't see this issue on Azure router-perf test
