I have been setting up remote probes at several sites recently, and am getting a consistent error across roughly half of the sites when it comes to the installation of the remote probe. Usually I run the remote probe installer from the machine, and in installs and connects no issue. However, on a few of the sites, once the installer reaches the "connecting to server" step, it will just wait there until the bar is full, and then display the error message, "Your remote probe could not successfully connect to the PRTG server in time".
For each occasion this has happened, I have created a inbound rule for the firewall to allow port 23560, but this does nothing. I have followed the manual for the remote probes but still cant determine the issues.
Just to reiterate that this isn't happening on every installation, for the most part it works fine and runs smoothly, but for a few it is having these issues.
Thanks for help.
