Hello everyone,
I am facing an issue where the AEM dispatcher is not serving the page from the publisher.
AEM setup is on-premise and non-prod. I had AEM 6.3.3.8 running with the dispatcher(4.2.x) on the Apache server, where the publisher and dispatcher are hosted on separate servers.
I had performed an upgrade of AEM from 6.3.3.8 to 6.5.9 (Because, the application project is built using JAVA JDK8). Now, the dispatcher is also updated to 4.3.3 as per Adobe's documentation.
The existing dispatcher configurations were not touched, I have replaced the mod_dispatcher.so file and restarted the dispatcher(httpd service restarted).
When requesting a page via the dispatcher, I always get a 502 gateway timeout. When I switched to debug mode, I found the below logs in the dispatcher.log file -

Also, when I performed the CURL command from the dispatcher - I noticed that when the URL contains HTTP protocol, I get an output as the letter "P" and when the URL contains HTTPS protocol, I get the output with the desired HTML.
Any pointers, where I should check further to solve the issue?
