Continuation of Failures

Help
1

I am honestly getting frustrated as my Pihole just stops working, My whole network points to it and i know when it goes down when i have no network.

I finally was able to do the pihole -d before rebooting it.

A reboot fixes it each time, I thought it was overheating so i added a fan but clearly thats not the issue.

I did have a post previously but had now replies so Iā€™m going to try again before giving up on this box.

Thoughts and help please :slight_smile:

Looks like FTL crashed at least once:

2026-03-27 05:54:19.110 CDT [43962/T43997] INFO: !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
2026-03-27 05:54:19.110 CDT [43962/T43997] INFO: ---------------------------->  FTL crashed!  <----------------------------
2026-03-27 05:54:19.110 CDT [43962/T43997] INFO: !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

The debug log shows only a few lines, but we can't see the crash details. We need more information.

Can you please run sudo cat /var/log/pihole/FTL.log | pihole tricorder, upload the file when asked and post here the new Token?

here is the new token: nqOn1X75

whats odd is i have had this pi4 for a while with no issues, then I started having some slowness and with the big update it was recommended to do a full clean install which i did. Was working fine for a while and then about once a week it would stop working again.

Try some stresstesting tools to see if it will crash or not.

Could be bad RAM or your Power Adapter having issues so check for Undervoltage Notifications too : raspberry pi os undervoltage at DuckDuckGo

I was originally thinking that it was due to the network being overloaded. This only happens overnight or towards the end of the night where we have the least amount of traffic.

No voltage issues but ill check the RAM when work is done. Thanks

@DL6ER

Can you please take a look on these logs?

I'm guessing here, but apparently FTL is crashing when the certificate is generated.

@patryk

Do you access the web interface via http or https?

As a test, can you please change FTL options to only use HTTP (80) port and check if the issue still happens?

Use this command to change the port:

sudo pihole-FTL --config webserver.port '80o,[::]:80o'

Does the crash still happen?
