How to make a replica slave member to be primary member?
Your problem is that one node of three cannot be "majority". If you remove those two nodes from setup, that one can become primary. Altho better solution is to get those two other nodes to response. 

That error message tells that this node (where you gave rs.status() -command) cannot connect to other two nodes. I guess that there is a firewall between and there is no hole for port 27017.

As always, the best source for the problem solving is mongodb.log file, where program tell you what is wrong with setup.
