[SR-Users] Playing with Diameter - Error opening connection to :3868

Mon Jan 28 15:46:58 CET 2019

Hello

Mra2 domain couldnt be resolved by cscf so cdp module couldnt bind to hss accepting port.  First of all , you should solve it. Probably your dns configuration is wrong or your bind/named server isnt working. You can test it with dig command. 

Good luck
