Unable to parse ip

As the forum search option is having a problem - I tracked down the issue for the “Unable to parse ip”-message with another user some days ago. The problem was an outdated version of FireMotD. Please have a look here:

You can try to run:

/usr/local/bin/FireMotD --version

The version I am using is:
FireMotD v12.05.191019

Additionally you can run:

sudo /usr/local/bin/FireMotD -S
sudo /usr/local/bin/FireMotD --theme Gray

This should at least solve the display-problem of the IP.
