RTMT application cannot communicate with specified node/cluster

Hi All,

We have just installed cucm version 12.

I've downloaded rtmt plugin but i'm not able to login.

I'm facing this message.

RTMT application cannot communicate with specified node/cluster.

Please verify the host IP address is correct and the network connection is up, and try again.

Any help would be appreciated.

I have found more success using RTMT on a linux virtual machine than on windows.

You probably would like to try that.

btw, RTMT uses an non-standard port, that could be blocked by the firewall also.

Hmmmmm ...

Hello Monasir,

Regarding this i would suggest you the below :

1. Please make sure we are entering the correct ip address/ hostname and password.

2 .Check for reachability from your machine that has RTMT installed to the server you are trying to login.

3. Try and logging from a different machine to RTMT,

3. Also you can try and clear certficates when the RTMT pop ups and chec if that works..

4. If issue still persist, try and re-installing the RTMT.

Thanks & Regards
