W2k24 print server with IPP enabled not allowing network devices to print to it

Question

A service we will be starting to use shortly requires a printer server with IPP/IPPS enabled on it to print securely. I have setup a Windows Server 2025 server with the printer server and Internet Printing enabled. After adding a network printer to the print server I can do a test print, but when I try to attached my PC on the network to use the w2k25 print server's printer the test print goes to the queue and just says ERROR. Can't find anything to tell me why it is failing. No logs, no useful info in the event viewer.

Only thing I noticed is the setup for IPP printed says you have to download the printers certificate and place in Third Party Root Certificates. However it get auto-deleted by the OS. I tried placing the certificate in the Root and Personal folders, no help. Don't even know the certificate the problem.

If anyone has setup a Windows Print Server with IPP printing, can you give me some help in identifying why nothing from any device other than the print server errors out.
