Error stating incompatible software versions between Probe and Core about pythonminiprobe

[konstantinpae]

What port are you using to connect the mini probe? Please note that the same is connected to the web server but not the normal remote probe port. Could you change the port used in the probe.conf file?

Currently I am using port 23560 for the connection. The firewall on the PRTG Monitor system has no restrictions for outgoing traffic and a rule to allow TCP incoming on port 23560. The wget command stated in the installation instructions works fine but shows an error due to the fact that there is a self-signed certificate in place.

On the PRTG Monitor the value 23560 is set on "Port für Verbindungen mit Probes".

On the RPi he probe.conf looks like follows:

###Mini Probe Config File
protocol:1
name:Python MiniProbe
cleanmem:False
server:-deleted-
gid:-deleted-
baseinterval:60
subprocs:10
key:-deleted-
debug:True
port:23560
announced:0

The port could be easily changed of course. So your suggestion is to change the port on both ends?

Ok, this explains the error message. The mini probes can only connect to the web interface of the PRTG core. Therefore it is neccessary the web interface runs secured with SSL. If this is the case, please change the line
port:23560
to
port:443
(or any other web server port you are using). Afterwards the probe should connect.

Worked just fine, thanks a lot! Just to dispel my misconception: What is "Port für Verbindungen mit Probes" for then?

You are welcome. Said port is for connections with "normal" remote probes which are running on Windows only. See the PRTG manual for details.
