Expected Behaviour:

piHole running with connection

Actual Behaviour:

In the web interface: message “Lost connection to API” , FTL offline and all chasing arrows
if I launch the command

I have

You appear to be out of space on the SD card

What is the output of df -h from the Pi terminal?

Here it is:

seems good for me

… and I don’t have rights to see what’s in
/var/log/lighttpd
with my pi account, using su

So I fixed the problem in recreating the system on the SD-Card and reinstalling Pi-Hole from scratch…
Sadly, it seems that this is often the only working solution when a problem occurs on a Pi :frowning:
