This error message indicates that PRTG did not receive any response for the HTTP call. When using the provider bulksms, check if your firewall is blocking outgoing connections and make sure connections on TCP port 5567 can go through to the provider's servers.

If changing firewall settings is a problem, you can also use the Enter a custom URL for a provider not listed option and enter the provider's URL using the default port number 80.

For more information, see https://www.bulksms.com/developer/eapi/


Which URLs does PRTG use for its preconfigured SMS providers?
