I would like to preface this by saying that I have not used PRTG a lot. I am doing a PRTG installation with 2 remote probes connecting to the Core server in a offline Windows environment.
Summarization of the environment:
- Browser: Microsoft Edge
- OS: Windows Server 2016
- Host A: Core server, IP: 192.168.1.1/24, Firewall = off (added port 23560 TCP inbound)
- Host B: Remote probe 1, IP: 192.168.1.100/24, Firewall = off (added port 23560 TCP outbound)
- Host C: Remote probe 2, IP: 192.168.1.200/24, Firewall = off (added port 23560 TCP outbound)
- Powershell: Host B & C can do a fully successful Test-NetConnection on port 23560 for Host A.
I have opened up all ports necessary for PRTG, but to make it work regardless I have deactivated the firewall as a whole on all 3 hosts. What happens is, the remote probe installer finishes successfully on Host B & Host C. Yet there is no activation screen on Host A. It starts a ticket on the Host A but that is about it.
When I open the ticket and click the Host B & Host C device, I can go to it but when I open Devices in general it is just an empty white space. There never is an option to approve the remote probe. Not in regular settings or overview nor in the Host B & C setting or overview.
Steps taken to solve the issue:
- Restarted all hosts
- Clean reinstall of remote probes
- Executed install as regular user and as administrator
- Restarted Core service before install of remote probe
- Checked to see if Core server is listening on port 23560 in CMD (answer is yes)
- Checked for any logs, but none that were usable to this issue have been found
Does anyone have any idea as to how I can fix this?
