"could not bind socket, address and port in use.



so my probe for netflow is not collecting any data and I get the error"could not bind socket, address and port in use..I have switched between ports 9991, 2155 and 2055. If I select assign a port and use netlow tester, I get an error..but if I use the tester with a port that is unassigned in the probe, I do not get the error. when I assign the port that I just tested in the netlow 9 tester (without any errors) and test again I get the error..

thank you very much for your KB-Post. It's normal, that when you run the Netflow Tester and a Sensor, to listen on the same UDP Port, only one of them will work. Only one application can listen/bind a port. That's not our limitation, this is Windows.
Which exact version of PRTG are you using?
Please try restarting the PRTG Probe Service after using the Netflow Tester. Do the sensors then start working?

best regards.
