I have a third party opc connection in ignition that is showing faulted. Initially the igniton opc UA certificate had expired so I regenerated it in igntion and then imported to the third party server. But I can't get it to connect now.
After regenerating the certificate, did you restart the Ignition OPC server or Ignition itself?

I restarted the third party opc server but not Ignition itself.
Try restarting Ignition OPC server or Ignition as a whole.
