Services do not start because binding on http://+6060/nospamproxy does not work

Error

For no apparent reason, the services of the NoSpamProxy suddenly no longer start. Re-installation does not work. The following error is displayed in the event log:

Description

The underlying transport for [::]:6060 cannot be bound. The list may contain a reference to an interface that may not be present on this computer for IP listening only. The data field contains the error number.

Status

This problem occurs in conjunction with IPv6. The "Net TCP Port Sharing" service will then no longer get a connection. The exact cause is still unknown.

Solution 1

1. Enter the following command on the command line:
   netsh http add iplisten ipaddress=0.0.0.0
2. Restart the Net at Work Mail Gateway services.

Solution 2

1. Enter the following command on the command line:
   netstat -ano >netstat.txt
2. Check in the netstat.txtwhether a process is using port 6060. If so, the corresponding PID (process ID) is displayed.
3. Use the task manager to find out to which process the PID belongs.
4. Clarify whether the process can be adapted accordingly or not.
