Extender Configuration of MaaS360 Fails

I got the credentials from Maas360 and installed proxy agent on a relay. When I enter credentials in “Configure Credentials” window and proceed action, the actions fails every time.

When i check the Management Extender’s log, there was this error:

Action <1810> running on computer <11079219> in plugin <MaaS360 Extender 1> was interrupted. Marking action as failed.

I am using version 9.5.5 relay and proxy agent.
