If you are Experiencing issues with a Pi-hole install that has non-standard elements (e.g you are using nginx, apache2 or another reverse proxy, or there is some other aspect of your install that is customised) - please use the Community Help category.

Expected Behaviour:

Access to web server should work.

Actual Behaviour:

I was on it, but then clicked on dashboard and it never loaded and then I had an uptime alert that it stopped responding.

This has been occurring a bit recently, like every few hours, if I ping that machine by name i get a failed, if I ping by ip it's up. This seems to be a bit intermittent

It does seem to be responding to dig requests made to it. So it could just be the web server crashing.

I thought maybe it was related to unbound which I have on this machine, but I've just set it to cloudflare dns - but that didn't have an effect.

Thought it might have been space related but it's fine.

I could look as resetting the DB and shrinking it if the site is being overloaded by the number of entries in the db.

Some more behaviour. It seems to go down hourly at 11 past the hour, and return by 00.

I can't see any recurring tasks on the device (in cron).

I do have a nebula-sync running (but that's every 15 minutes) and I'd just disabled that.

I’ve taken a debug when it’s not responding as well.

https://tricorder.pi-hole.net/IBbDyShG/

so web server is not responding- but nothing seems to appear in the logs. It’s is getting dns name not found but internet access and other local dns lookups are still working.

Oh, it’s very strange. I can dig google at that pihole (I have 2). And it answers. And another local server. But if I dig its name I get no answer
