Windows dynamic port range
The Trust1Connector is using 3 different network ports for communication, For the Trust1Connector by Trust1Team these are ;
Registry, fixed
51983
(51883
for the acceptance version)API, dynamically assigned
Sandbox, dynamically assigned
In some rare cases the windows system prevents a range of TCP ports to be used by applications, this is called an exclusion range.
You can see the dynamic port range by executing the following command in a terminal
netsh int ipv4 show dynamicport tcp
The output will look like the following
Protocol tcp Dynamic Port Range
---------------------------------
Start Port : 49152
Number of Ports : 16384
For the exclusion range you can use the following command
netsh interface ipv4 show excludedportrange protocol=tcp
This can look like the following, this can differ from your system
Protocol tcp Port Exclusion Ranges
Start Port End Port
---------- --------
53180 53189 *
* - Administered port exclusions.
To remove the listed port ranges from the exclusion range you can use the following command.
netsh int ipv4 delete excludedportrange protocol=tcp startport=51980 numberofports=10
This will make sure that starting of 51980 there are 10 ports allowed to be used by other applications.
If the steps above did not solve your issue you can also update the dynamic port range with the following command. This will move the port range to start from 54000 and have 10511 available ports to be used.
netsh int ipv4 set dynamic tcp start=54000 num=10511
