Before submitting a bug report, are you using a test version of Pi-hole? If so, PADD doesn‘t support beta versions of Pi-hole!
Newest version - non beta

Describe the bug
Everything starts and works perfectly. But, I'll come back and look at the display a few hours later and see this error.

To Reproduce
Steps to reproduce the behavior:

1. ... Start and run PADD.
2. ... Wait.

Expected behavior
Errors occur - pictured in screenshot.

Happend after 8 hours 30 mins up time.
Running:

Edit: This was a fresh install of PADD, never installed on this Pi before.

I am also receiving this error after installing a new 3.5" display

http://www.lcdwiki.com/MHS-3.5inch_RPi_Display

Pi-hole 5.2.1
Web interface 5.2.1
FTL 5.3.2
PADD 3.4

Error message -
./padd.sh: line 126: /dev/tcp/localhost/4711: Connection refused
./padd.sh: connect: Connection refused

Previously I was using a 2.8" Adafruit display and never received the error.

Edit - 11 Dec 2020

Using htop I found and killed the erroneous padd process running under the pi user.

I then restarted padd > ./padd.sh > tty1

It has been running fine overnight with no errors.

Something else I noticed. When the error occurs the CPU temp goes up to 75+ degrees C.
After restarting padd CPU drops to ~54 degrees C

Hi there,

After using PH with PADD for over 2 years, this issue has suddenly popped up, randomly every few days.

I can also confirm the CPU Temp increase, maxed out memory, screen looks the same as the top screenshot. I can connect with Putty and do the reboot command, restarts fine till next time it occurs, only warning i get is internet goes down, also note tonight's case happened at about the same time i disabled PiHole via the web interface for 5 mins to test a connection issue (to see if i needed to whitelist a domain).

Any updates on the fix?

Thanks

Dash

There's no problem at my installation running padd.sh for a week or sometimes two weeks (if no maintenance with restart/reboot was neccessary of Pi-hole or operation system)… 🤷🏻‍♂️

So is this still an issue for you?

Not me, but I recently had the same issue start up with me. No idea what's caused it.
