PiHole directing own domain to 127.0.0.1

[Epowerj]

Hardware: VPS bought online
YunoHost version: 3.6.4.6
I have access to my server : Through SSH + through the webadmin
Are you in a special context or did you perform some particular tweaking on your YunoHost instance ? : no

Description of my issue

I recently installed PiHole on my yunohost with default settings, not using as a DHCP server. It works great, except when I try to access the server through the domain I have pointing at it. In other words, while using the pihole DNS server, when going to mydomain.tld (which points to the yunohost install on a vps), I fail to connect. When going to any other domain, it works as expected.
I pinged my domain while using pihole DNS, and found out that it’s trying to go to 127.0.0.1.
I noticed that the settings page on my pihole webportal shows: (not shown is my domain)
I assume that the ip should not be set to localhost, but rather the server’s external ip. It seems that normally you would do pihole -r to reconfigure pihole, but that doesn’t seem to work on yunohost:

$ sudo pihole -r
(after going through ncurses ui)
[i] Logging On.
[i] Performing reconfiguration, skipping download of local repos
[✓] Resetting repository within /etc/.pihole... 
Unable to reset /var/www/html/admin, exiting installer

I feel that this can’t be an uncommon problem, since it happens consistently with default install, but I haven’t managed to find any help.

Does anyone know how I can fix this issue?

hmmm and so from your server, is your domain name resolved to 127.0.0.1 or to the global IP ?

If I ping my domain name from the VPS that yunohost+pihole is running on, it tries to reach the external IP of the server.

It might be worth mentioning that this might be an intended feature, as mentioned here:

As you’re going to use your own dns, when you will try to connect to your server, your dns won’t return you your public address like any dns server. It will return you the local address of your server, so it will not needed anymore to deal with your hosts file to use your own server !
No more hairpinning problems !

Hi

That may be more a problem with your /etc/hosts than pihole’s config.
The hosts file on your server resolve any local domain you have to its local address.
As you use a VPS, you should probably comment those lines.

This fixed the issue, thanks!

I set manage_etc_hosts to false in /etc/cloud/cloud.cfg then added “myipv4 domain.tld” and “myip6 domain.tld” to the /etc/hosts file, and everything seems to work fine now.
