Unable to establish connection from domain --> Dispatcher --> Render ..502 Bad Gateway

Hi Team,

We are using Apache version 2.4 with dispatcher 4.3.3 version. Configured dispatcher.any, httpd.conf,http_Vhost.conf, when we are accessing from dispatcher I am able to get response from renderer. But when we are accessing from domain i am getting 502 bad gateway. In dispatcher.log response status coming as 400. Please help me on the same. 

When accessing from dispatcher find logs

    The error is created on AEM side, so you check the logs there.

    * The request.log on that publish instance should log this request with the response code 400 as well.

    * Check the error.log if there is any trace for that request.

     

    What code is behind this /bin/healthchecktype=external request? I am quite sure that it is not AEM ootb functionality.

    Please check the following document where the steps to use dispatcher with multiple domains is explained:

    Hi Hamid, Thank you for your quick response. I have followed the same documentation. But no luck. Please suggest me any other options.

     

    Note that I am able to establish request from dispatcher to renderer but unable to establish from domain via dispatcher to appserver.
