Problem with inventory look up and stock count on POS

Hello All,

I recently installed a Retail POS client fro my development environment.I installed the real time service and all the other components.I created a self signed certificate for my development environment.The problem that i encounter is that when i press the stock count on POS I get the following error.

TS invoke metod failed due to CommunicationException:GetInventJournals()

similarly when i do the inventory lookup i get the following error

Error No:13010 Could not connect to the transaction service.

I tried uninstalling/installing the real time service various times but it is still not working.

I am working on AX 2012 R3 CU 10.

I am stuck in this for two days now ,kindly please help me.
