To resolve the issue:

  1. Check that your API server is working by executing
    sv status api-server
    If service is stopped - please restart it. If service is not launching - please refer to the logs to see the error
  2. Check that correct domain name is specified in the Admin panel (Account Management -> Service preferences)
  3. Check API URL, it may be incorrect URL in the Config.js. File is located in web server's root directory, usually it is /var/www/pro-ui. Replace with correct one and reload the page
  4. If all points above are fine - please check memory consumption and API log. Perhaps, service has run out of memory.

To know what error occur please start browser console pressing F12 (chrome and similar) then click on “Network tab” and choose red message. Clicking on the “Preview” you’ll see the answer from API. Mostly it is caused by error “Dealer not found”. In the admin panel, go to Service Preferences tab in the Account Management section, and insert your domain used for monitoring and save. It will be OK.
