Make sure AEM is not running twice on the same port.

Hi,

Looks like the port 4502 is already in use.

You can take a look at the official documentation to see how to change the default port and start over that.

Further, to find the process using the port, you can run cmd.exe as admin and run "netstat -abo"

It will have an output like this. The PID is the far right number

TCP 0.0.0.0:4502 THISPC:0 LISTENING 2708

[java.exe]
