 # Connection Log or device name on devices page of web console is empty
 Actually it is the same problem as above, [set correct `API` (the same as web console address)](https://github.com/rustdesk/rustdesk/wiki/FAQ#failed-to-log-in-with-custom-client-build-or-public-release-with-wrong-api-settings), you have wrong API settings (please check controlled side for connection log issue). 
 
+The simplest way to verify the API configuration is to log in on client and check if you encounter any error messages as https://github.com/rustdesk/rustdesk/wiki/FAQ#failed-to-log-in-with-custom-client-build-or-public-release-with-wrong-api-settings
+
 > Please double confirm the API address used for building the custom client, especially some were built before you configured https or domain etc.
