Things to check that AJP works properly on the Axon.ivy Engine side:

Check that AJP is Enabled

and verify that you try to connect to the correct Port. By default AJP is enabled and bound to TCP port 8009.

you can the AJP settings in the EngineConfigUI:
or in the Admin UI. See System Properties > Webserver.AJP.Enabled and Webserver.AJP.Port.
changes on these properties (EngineConfigUi oder AdminUI) always require a restart of the Engine to take effect!

Verify that the TCP Port was bound

By default this is TCP Port 8009 which must be bound during the Engine boot and is waiting to receive packets.

on windows: execute netstat
on linux: execute lsof -i
if the port is not bound. Try to log the AJP connector bootstrap to get more results: https://answers.axonivy.com/questions/3318/how-to-log-ajp-connector-bootstrap

Examine IIS <-> Axon.ivyEngine communication

Enable isap-redirect trace logging to examine in detail the communication between the IIS and the Axon.ivy Engine.

Go to your IIS integration directory. By default [engineDir]/misc/iis/isapi_redirect-1.2.42.properties. In a productive installation you hopefully have copied that directory to another location outside your current installation directory.
Adjust the content of the file. Set log_level=debug, save it. And fire a request against the IIS frontend with your browser.
