Basic Authentication for SMS Delivery

If you are encountering authentication issues when using custom URLs for SMS notification delivery, it may be helpful to change the authentication type. This is because some providers require basic authentication. For this reason, we provide a registry key that allows you to do this. If you apply this registry hack, you will be able to use basic authentication for SMS delivery.

Caution: Please back up your system before manipulating the Windows registry!

  1. Open the registry editor and navigate to the following key:
    1. On a 64-bit Windows system, navigate to HKEY_LOCAL_MACHINE\Software\Wow6432Node\Paessler\PRTG Network Monitor\Server\Core
    2. On a 32-bit Windows version, navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Paessler\PRTG Network Monitor\Server\Core
  2. Create a new DWORD: in the current path, right-click, choose New | DWORD Value, and name the new value CustomSMSBasicAuth.
  3. Set the value of CustomSMSBasicAuth to 1: right-click on CustomSMSBasicAuth and select Modify.... In the value data field, enter 1. Confirm with Ok.
  4. Restart your PRTG core server.

Setting the value of the DWORD to 0 (or deleting it) will disable basic authentication for SMS delivery again.
