[ovirt-users] Major screwup and now I can't bring anything up

I have a small home oVirt 4.5 deployment that was struggling a bit and I think I've only made things worse. I was seeing some SSL errors in various places but couldn't find any evidence of an expired cert though maybe I overlooked something. At present, it looks like the most immediate problem is that the engine.log is showing SyncNetworkProviderCommand fails saying EngineException: (Failed with error Unsupported or unrecognized SSL message and code 5050). For now, I'm only concerning myself to one Host that had been running VMs until I tried restarting everything from a power off. I take it that the sync failure prevents this Host from becoming active. I had successfully been using this setup for many years. I do have my own web cert on the engine signed by my CA. While I was getting this same "code 5050" error before with things like ovirt-imageio (what prompted my initial digging), now I'm afraid I've only made things more complex. See, I was running FreeIPA on a pair of VMs. In the past, this pair of VMs would auto-start once the oVirt Engine and Hosts were going and I had no issue. But now I wonder to what extent OSCP being unreachable might affect the SSL errors. What's the best/easiest/safest way out of this mess? Should I just wipe ovirt-engine of all the non-rpm provided files in /etc/pki/ovirt-engine/ and redo the engine-setup? I'm afraid of making things worse before I begin attempting that.
