Adobe Experience Manager Sites Architect Master

On release day, an AEM code deployment is performed on an on-premises AEM 6.5 environment. After deployment completes, users can access the Author instance without any issues. However, users cannot access any sites through the public domains and receive a 502 Bad Gateway error.

What could be the potential cause of this issue?

Explanation

AEM Dispatcher acts as a reverse proxy to Publish render instances. Its /renders configuration specifies the Publish hostnames or IP addresses and ports to which public requests are forwarded. If a newly deployed Dispatcher configuration points to the wrong Publish instances, Dispatcher cannot reach the intended backend and public requests can fail with a gateway error while Author remains accessible.
