Discovering CUCM and IM&P From Expressway C

[luismgallop]

Hello Guys, 

I'm trying to discover my CUCM and IM&P server from expressway C, and I can't do it. I already upload on Expressway C the Tomcat certificate from both servers and the restarted Expressway C, but is not working, it shows me the netx message: 

The certificates are self signed from each server (IM&P and CUCM).  

The CUCM can be reached it using the Ping tool, but I don't know what is happening. I got the same error whith the IM&P server. The Expressway version is 8.7. CUCM and IM&P version is 10.5.2. 

If someone could help me with this, that would be great. 

Thanks,

Are you sure you have the proper DNS working?? That's not even complaining about certs, that's basic connectivity 

Anything that could be blocking communication between servers??
