The automatic license activation of my PRTG Enterprise Monitor license does not work. What can I do?



Your Vote:



I use a Paessler PRTG Enterprise Monitor license and have a license activation issue. The license does not seem to update automatically. When I go to Setup | License Information in the PRTG web interface and click Refresh Information, I get the following error message:

License has expired. (Failed to establish secure connection Socket Error #10060 Connection timed out.)

What can I do?

Automatic license activation in proxied environments after a PRTG core server restart

If you have a Paessler PRTG Enterprise Monitor license and use a proxy server, it might happen that the automatic license update and activation do not work. The reason might be that PRTG cannot access your proxy settings after a PRTG core server restart.


First, go to Setup | System Administration | Core & Probes in the PRTG web interface and make sure that the proxy configuration is correct. If this is the case, please use the following workaround:

After a restart of your PRTG core server, go to System | License Information and click Update License to manually update and activate your license.

This way, PRTG can access your proxy settings and the automatic license update works until the next PRTG core server restart.
