Licensing with active Proxy

An active internet connection is required for automatic licensing, and a connection to the signotec licensing service must be possible. Licensing can also be carried out if internet access is established via a proxy server.

The software automatically uses the proxy server configured in Windows, so no special settings or adjustments are usually required. Both manually configured HTTP, SOCKS4, and SOCKS5 proxy servers, as well as automatic proxy configurations via PAC or WPAD files, are supported.

Licensing Process

The software transmits the entered or stored license key, along with current device information, to the licensing server (https://licence.signotec.com) via a REST API (HTTPS, 443).

The server responds with an XML structure (Content-Type: application/octet-stream). Depending on the result, the response contains either a positive or negative validation. In the case of a successful license validation, the XML data is saved as a file locally on the computer. By default, the following directory is used: %ProgramData%\signotec\Licenses. If write permissions are not available in this directory, the following alternative is used:%AppData%\signotec\Licenses.

Troubleshooting / Exception

If licensing fails despite an active internet connection, it is likely that communication with the licensing server or the reception of the license data is being blocked—possibly because the proxy or firewall interprets the data transfer as an unauthorized download. In this case, communication must be explicitly allowed as an exception in the proxy or firewall security settings. This configuration must be carried out by the responsible system administrator.

If automatic licensing does not work even though an internet connection is available, please verify the following:

• Is the proxy server correctly configured in Windows, and is the type of proxy supported by the signotec software (HTTP, SOCKS4, SOCKS5, PAC, WPAD)?

• Is access to the URL https://licence.signotec.com (port 443, HTTPS) permitted?

• Is a firewall or proxy server blocking the download or storage of XML data (Content-Type: application/octet-stream)?

• Does the user have write access to the following directory?

  • %ProgramData%\signotec\Licenses or alternatively %AppData%\signotec\Licenses

If no internet connection or exception configuration is possible at all, a manual offline licensing process must be carried out. In this case, please contact us at: lizenz@signotec.de.
