I am getting the following error in AEM author, when trying to access pages through dispatcher.

503 - Bad Gateway

The proxy server received an invalid response from an upstream server

and 504 in publish.

please see the dispatcher logs below.

Hi Anusha

Could you please check if the author/publish server is not blocking traffic from dispatcher? You need to white-list dispatcher server.
