Resolution

This error occurs when the values assigned to ports client.serverPort, server.serverPort, and server.serverFixedPort are inconsistent in the file <installDir>/Composer/composer/properties/composer.properties.

Example:

client.serverPort=4001
...
server.serverPort=4002
server.serverFixedPort=4001

You must change like this:

client.serverPort=4001
...
server.serverPort=4001
server.serverFixedPort=4002

The values assigned to ports client.serverPort and server.serverPort must match while the one assigned to port server.serverFixedPort must be different.
