Telemetry Login Error

I have an APM 2.5 and downloaded the latest Mission Planner(32-bit) on Win 10 (64-bit). I am not able to connect APM to mission planner using telemetry but able to connect using the USB cable. I have also installed CP210x_Universal_Windows_Driver (64-bit).
Any suggestions as to how I can debug the problem?

I have solved this issue, there was a driver problem
