The Mini Probe which runs on my Android device cannot connect to the PRTG core server. The mini probe reports that it requires SSL. However, I have deactivated SSL encryption on my PRTG core server because my network scenario makes use of other security components.

How can I connect my mini probe to the core server without using SSL connections?

android connection connectivity https mini-probe prtg reghack registry ssl

PRTG Mini Probe Connections without SSL

PRTG Mini Probes require HTTPS connectivity to send monitoring data to your PRTG core server. Mini probes cannot connect when SSL is disabled for PRTG. This is essential for the connection security because probably unencrypted passwords will be transferred. So it is important that all connections are encrypted between core and probe, even on internal routes.

However, there might be scenarios where full security is ensured in other ways (for example, via VPN etc.). For these cases, in order to get connectivity with mini probes, there is a registry key option available to define SSL as not required. It has to be set explicitly, being fully aware of the effect.

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

Steps to Go

  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\Probes\
    2. On a 32-bit Windows system, navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Paessler\PRTG Network Monitor\Server\Probes\
  2. Create a new DWORD: in the current path, right-click, choose New | DWORD Value, and name the new value MiniProbeSSL
  3. Set the value of MiniProbeSSL to 0 (this means no SSL required): right-click on MiniProbeSSL and select Modify…. In the value field, enter 0. Confirm with Ok.
    Note: The value 1 will set SSL to be required for mini probes.
  4. Restart your PRTG Core Server to activate the settings.

Now your PRTG Mini Probe will be able to communicate with your PRTG core server without having HTTPS connectivity.
