Ok, so this is the same system that has the wrong ssh login context
(per your Current context" and "Controlling terminal" lines above. So
likely the same root cause as that problem.  Look for sshd errors in
/var/log/secure or journalctl, run selinuxdefaultcon as I described to
see whether you can reproduce the incorrect context computation.
