PJSIP extensions not working after v14 -> v16 restore

After a restore of v14 to v16, our pjsip extension are all unavailable. If I do a “pjsip show contacts”, I see something like this:

Contact: 190/sip:[email protected]:5060 665b60c67b Unavail nan

We had no issues with pjsip endpoints in v14 and they had always been that way so I’m not sure what is going on.

It should be noted that at one point the contact list was empty and I was seeing the “Unsupported transport (PJSIP_EUNSUPTRANSPORT)” that has been posted about but a complete server reboot now has me back to this point.
