Systemmonitor - IndexError: list index out of range

Configuration

When I start I get this message:

How can I find out why this message appears ?

Can you paste your system monitor config here please? (please use the code blocks to format the code)

  display_options:
    - 'time'
    - 'date'

Needs indenting by 2 spaces, hopefully that will fix it :slight_smile:

Negativ, i have 2 Rasperry running, same configuration. One is working w/o errors.
The 2nd shows this errors.

I don’t uses systemmonitor, but just looking at this line of code it looks like it is a problem with the number of IP addresses on this machine. Is it running both IP4 and IP6?

Running ifconfig -a on each machine might reveal some differences.

Thank you, it was the IPV6 address, this is not enabled on the second Raspberry. I have removed these from the configuration and now the application starts without the error.
