Error in configuring Power BI Gateway - Enterprise (Preview)

I have installed PBI enterprise gateway and signed in to PBI account successfully.

I found error in configuring as following:

Failed to update gateway details.  Please try again.
This request operation sent to net.pipe://localhost/powerbi/gatewayconfiguration/service did not receive a reply within the configured timeout (00:01:00). The time allotted to this operation may have been a portion of a longer timeout. This may be because the service is still processing the operation or because the service was unable to send a reply message. Please consider increasing the operation timeout (by casting the channel/proxy to IContextChannel and setting the OperationTimeout property) and ensure that the service is able to connect to the client.
