Pi-Hole Enhanced app not pulling any data despite working API connection

[nightchrono]

I have created a pi-hole enhanced app on a Heimdall instance running on apache2 on an Ubuntu 22.04 VM. I actually have two pi-holes, one running on a raspberry pi 4, and one running on a ubuntu VM.

I can test and verify the API token, but no statistics are shown in the dashboard.

Cleared the cache, restarted Apache, reboot the whole server, and tried multiple browsers.

@nightchrono What version of pi hole and heimdall are you using?

Heimdall 2.5.7
Pi-hole FTL 5.22

[nightchrono]

Sorry, this is probably what you were after:

PI-HOLE V5.16.2
FTL V5.22
WEB INTERFACE V5.19

Forgive the caps lock, was copy/pasting off the footer.

Im having the same issue.

[kennychan-git]

solved. in the URL, use something like this http://10.0.0.1/admin/

[nightchrono]

In my initial screenshots I was using /admin in the URL. I also tried using just /admin without the API specific link and it also does not work

Having the same issue. I've tried all sorts of incantations with the URL for the api: api.php, just /admin, api.php?summaryRaw, etc and still nothing. Can confirm that I can reach the api endpoint and get data back from within the Heimdall docker container.

root@15748f5faa60:/# curl "http://piholehost:8888/admin/api.php?summaryRaw&auth=<TOKEN>"
{"domains_being_blocked":503439,"dns_queries_today":6145, [...]

Do the logs from the PHP Laravel Framework log something?
Should be under /path/to/your-heimdall-folder/storage/logs

I see lots of errors in the log, but I don't know what any of them mean or what you would be looking for.

Want me to upload the log? I did a quick glance and didn't see my API key in it so I don't think there is anything sensitive in there.

[ChrLau]

I don't think the whole logfile is necessary. Can you execute the following grep command on the most recent logfile?
grep local.ERROR laravel-2023-MM-DD.log (Replace MM and DD accordingly.)

That should show the first line of all error messages. You can then post them here. (Just one per type. We don't need the same error posted 100 times. ;-) )

And another quick question: Did you try entering http://ip.of.your.pihole/admin/ as the URL and leave the the URL field at the bottom (where you enter the API-Key) empty?
That's how I have it configured and it works.

Just changed the URL as suggested and it did not have any effect. Still not pulling data.

[ChrLau]

Ok, the variable stdClass::$ads_blocked_today gets it's value from the details variable. The details variable contains all data Heimdall received from the Pihole-API. But it decodes that data via json first.
See line 27: https://github.com/linuxserver/Heimdall-Apps/blob/master/Pihole/Pihole.php#L27

Which Linux distribution are you running? Is the PHP JSON extension installed?

[nightchrono]

Two of them are ubuntu and one of them is raspbian

Php json was already installed when I tried on each machine to run "sudo apt-get install -y php-json"

EDIT

Ubuntu 22.04.3 and Raspbian 5.10.103-v71

[ChrLau]

Wait.. 3 hosts? Does that mean you have Pihole installed on all of them and the same problem on all of them?
Is Heimdall able to reach all 3 of them?
Do you use a separate API-Key for each Pihole instance?

Do you get a result when you execute the following command? (Replace with our API-Key)
curl "http://ip.of.your.pihole/admin/api.php?summaryRaw&auth=<TOKEN>"
