# Troubleshoot the Connector

This section describes how to troubleshoot common problems that might occur when you set up the Web Connector.

The synchronize log shows the error "Address already in use"

You might see this error if the system has allocated all available TCP ports.

Operating systems typically allocate a limited number of ports to applications that need to make outbound connections. Also, when a connection is closed, the operating system waits before a port is released and can be reused.

If you encounter this issue on a Windows system, you can set the Windows registry parameter `MaxUserPort`, so that more ports are available for use. You could also shorten the amount of time that the operating system waits before releasing a port by setting the registry parameter `TcpTimedWaitDelay`. These are both set in:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
