Webserver and agent on the same device

Hi,
I’m setting up an on premises system for the first time, and have a requirement to run both the Webserver and Agent on the same machine.
When trying to configure the agent in the Webserver, I get the classic “Server Error (500)”.
Is there an obvious error here? Do I need to run the Webserver and Agent on seperate machines?

Any help is appreciated!

your not the only one. the URL path is get it on is /configure/agents. when i select configure it directs me to “server error (500)”
