Unable to open debugger port in IntelliJ

Question

Unable to open debugger port in intellij. The port number 9009 matches the one which has been set in the configuration file for the application.

Answer 1

You may have to change the debugger port if your port is already used by another program. To do so:

• Run
• Edit Configurations
• Startup/Connection tab
• Debug
• Change the port here

Or, maybe in other versions:

• Run
• Edit Configurations
• Remote > Remote debug in the list on the left
• Configuration tab, Settings section
• Port: change the port here
