Fiddler Port in Use

Unable to bind to port [Localhost:8889]. ErrorCode: 10013.

This is usually due to another service running on this port. Run NETSTAT -A at a command prompt.

If you don't want to stop using the other program, simply change the port used by Fiddler.

Click Tools > Fiddler Options > Connections, select a new port, and restart Fiddler.

Does your system have a firewall product installed? This error message can be shown when opening a listening socket is prohibited by firewall rules. Try exempting either Fiddler or the port you plan to listen on.
