We're using PRTG Version 20.1.57.1745+

Auto-discovery occurs periodically even though the sensor is added using the procedure below.

1) Adding a device

2) Checking No auto-discovery

3) Adding a ping sensor manually

4) Done

Auto-discovery TCP/UDP Port lists

TCP 21, TCP 25, TCP 80, TCP 110, TCP 143, TCP 443, TCP 465, TCP 993, TCP 995, TCP 1521, TCP 3389, TCP 6200, TCP 8080, UDP 53, UDP 623

How can I prevent Auto-discovery (or portscan) from occuring?

Is the device perhaps within a group where the auto discovery is actually enabled, like the default Discovery group(s) after a fresh install?
