[en] When you try to start the HTTP trigger in Automation, you get an error message:
[en] "It isn’t possible to start HTTP server at port 54321, access was refused."
[en] or
[en] "Cannot start HTTP server on port: 54321. System error message: The process cannot access the file because it is being used by another process."
[en] The error occurs if Automation runs with limited user rights or some other application uses the port or the port is excluded from the available port list.
[en] Limited user rights, solution 1
[en] Assign NiceLabel Proxy Service 10 to a user with administrative permissions. Go to Services > NiceLabel Automation Service 1> Log On tab. Select a user with administrative privileges in This account section.
[en] Limited user rights, solution 2
[en] If you don't wan't to assign NiceLabel Proxy Service 10 to a user with administrative permissions, you can still run the service by enabling a specific port to this user.
[en] Run Command Prompt (CMD) application as administrator and use the following syntax:
[en] netsh http add urlacl url=http://+:56425*/ user=MyAutomationLimitedUser
[en] where 56425 is a port number and MyAutomationLimitedUser is a user name with limited rights.
[en] Other application uses the port
[en] If you get the error message "The process cannot access the file because it is being used by another process.", you can check which application uses your Automation trigger port.
[en] Run Command Prompt (CMD) application and use the following syntax:
[en] netstat -ano | findStr "6772"
[en] where 6772 is a port number.
Exemple 5. [en] Example
[en] Port 56423 is open and you can use this port with the Automation trigger.
[en] The process with PID 5168 is listening to port 6772 so the Automation trigger can't use this port.
[en] Port is excluded from the available port list
[en] Some applications, like Docker for Windows or Hyper-V can reserve ports, and other applications can't use them.
[en] To check if the port is on the excluded port list, run Command Prompt (CMD) application as administrator and use the following syntax:
[en] netsh interface ipv4 show excludedportrange protocol=tcp
[en] Command Prompt will list all excluded ports.
