You Asked for Port [xxxxx] in Your server.json but It’s Already in Use

[DaveL]

This is strange. I have a CommandBox site that I have used for years, but for some reason today I am getting the following error:

You asked for port [60830] in your server.json but it’s already in use.
Please choose another or use netstat to find out what process is using the port already.

I checked netstat, and even the GUI tool tcpview, and don’t see anything using port 60830.

Normally I would just change the port in server.json, but this is a REST API site that I have a few other Commandbox instances configured to access it which depend on the port. Is there another workaround for this error?

Here’s what I tried so far:
server start --force
server forget and server start

Neither attempt worked.

Run

server info --verbose

to see if there’s more info. Sometimes I’ve had issues with the Java networking stack that’s required an OS restart to clear.

Interestingly enough, disconnecting from my VPN did the trick and released the port. Thanks for the reply, Brad! Happy holidays.
