This guide provides methods to troubleshoot the OSTO Licensing system, particularly focusing on ensuring the accessibility of the licensing server URL, checking port activity, verifying subscription keys, and service status through the Event Viewer.

Verify URL Accessibility

To check if the licensing server URL https://api.erp.accessacloud.com/osto-licensing is accessible:

  1. Open Command Prompt. Press Win + R, type cmd, and press Enter.

  2. Ping the URL. Type ping api.erp.accessacloud.com and press Enter.

  3. Use Curl to Test the URL. If available, type curl https://api.erp.accessacloud.com/osto-licensing to get a response from the server.

Check Port Activity

To see if anything is running on port 18555, you can use the netstat command:

  1. Open Command Prompt as Administrator. Right-click the Start menu and select Command Prompt (Admin) or Windows PowerShell (Admin).

  2. Run Netstat. Type netstat -aon | findstr :18555 and press Enter. Look for any entries with LISTENING under the State column, which indicates something is running on port 18555.

Verify Subscription Key

To check the subscription key for the OSTO Licensing service:

  1. Navigate to the Configuration File. Open File Explorer and go to C:\Program Files (x86)\OSTO Licensing App\.

  2. Open appsettings.json. Right-click on appsettings.json and choose "Open with" > "Notepad" (or any text editor of your choice).

  3. Check Subscription Key. Look for a line named something like "SubscriptionKey": "<your_key_here>". Ensure this key matches the one provided for your service.

Service Restart

To ensure the licensing service starts correctly:

  1. Open Services. Press Win + R, type services.msc, and press Enter.

  2. Find the Licensing Service. Scroll through the list to find the "OSTO Licensing App" service.

  3. Restart the Service. Right-click on the service and select Restart. If the service is not running, select Start.

Check Event Viewer

After attempting a service restart, check the Event Viewer for any related events:

  1. Open Event Viewer. Press Win + R, type eventvwr.msc, and press Enter.

  2. Navigate to Application Logs. In the Event Viewer, expand Windows Logs and select Application.

  3. Filter for Licensing Service Events. Right-click on Application, select "Filter Current Log...", and enter the source name related to the OSTO Licensing App — this could be the service name or another identifier used in the log entries.

  4. Review the Events. Look for any error or warning events that could indicate issues with the licensing service starting up or operating correctly.
