ERROR message on pihole -c | Overheating pi!

i get this strahnge error message under the grap:

/opt/pihole/chronometer.sh: line 30: read: read error: 0: Connection reset by peer

came just after i updated the pihole version

Really strange is that it is building up more and more heat!!! cant cool t down anymore!!
(only pihole is on my pi)

Everything is connected to FTL nowadays. Try restarting pihole -c since your FTL is running now

i did it is working now it also cooled down
can you just help me out here?

Solved by the following steps:
pihol -r
and
reboot -n
