The default ports in Windows installations are 8081 for HTTP requests and 8443 for HTTPS requests.
To change the listening ports:
HTTP_PORT=8081 HTTPS_PORT=8443 HTTPS_509_PORT=8883
Note: The next time Sintelix is installed, the installer will pre-fill the port number fields in the wizard with the defaults that were accepted or the port numbers that were entered during the previous installation. Check that the port numbers are correct before you click Next.
