Today I changed my local network.
I configured the connection with the Davis station in TCP/IP like this: 192.168.1.101
Problem, by entering this IP address format, the VP2TCPPort=22222 parameter changes to VP2TCPPort=0 in cumulus.ini
This prohibits the connection during a next restart.
According to my tests, this happens when there are 3 digits at the end of the IP address.
Please consider this issue.
Cumulus MX 3.14.1 b3160
