ptc_d exited with status 34 (invalid host)

Greetings-

I inherited a RHEL 7 license server with several instances of lmgrd running various vendor products including creo. The existing license was expired, got a new license generated changed the Server/Daemon lines for server name/daemon path and restarted the service. 

In the logs I see ptc_d exited with status 34 (invalid host)

I have verified that the MAC address is correct, and goggled the error. The only reference I see for a status 34 was from 2017/RHEL 6 which I'm skeptical if its still relevant. Downloaded the latest LMGRD & ptc_d from PTC with no change. I'm at a loss on this one, can someone give me shove in the right direction?

Thanks in advance,

I saw that article, from 2017/RHEL6 era. I was hoping that after 8 years someone would have done some coding correction and fixed that. Guess not.
