Issue with connecting to host from container or no internet (nextcloud aio, podman 5.2.2 & 5.3.1)

[Extarys]

I'm trying to setup nextcloud-aio for two users. userA and userB, each having a linux user with a quadlet file.

I'm on Rocky Linux and I tested on podman 5.2.2 and I also installed Podman 5.3.1 because I heard container<>host was easier with 5.3.x.

For this example, let's call my domain usera.domain.local.
Caddy is installed natively, and I can connect to nextcloud but Onlyoffice doesn't work. It requires a loopback / calling the host it's installed on. ie https://usera.domain.local from within the container.

I don't have the errors I had with 5.2.2 on hand, so let's focus on the latest and greatest :) I must say, after updating to 5.3.1 (I used the CentOS rpm, no issue installing), I did some testing (see below) then I thought I should delete and recreate everything - but now there is no internet connection inside the container it would seem, I cannot ping or anything and nextcloud apps won't install.

The officiel nextcloud AIO readme file state that podman isn't supported, but it appear that many was succesful. I have no clue why this isn't working in my case.

I'm asking here because I know this is the best community to help me figure this out.

Quadlet

[Install]
WantedBy=multi-user.target default.target

Before install Podman 5.3.1, I was on 5.2.2 and from inside the host I could ping the domain, but curl -I usera.domain.local wouldn't work. Now, both ping and curl doesnt work on 5.3.1, I get bad host.

nslookup is now similar:

# nslookup usera.domain.test
;; communications error to 10.89.0.1#53: timed out
;; communications error to 10.89.0.1#53: timed out

With 5.3.1, before reinstalling

In Nextcloud I get:

Error when trying to connect (cURL error 7: Failed to connect to usera.domain.local port 443 after 10002 ms: Could not connect to server (see https://curl.haxx.se/libcurl/c/libcurl-errors.html)

When I try to add host-gateway:

Dec 13 22:45:28 nextcloud[179628]: Error: failed to create new hosts file: unable to replace "host-gateway" of host entry "usera.domain.local:host-gateway": host containers internal IP address is empty

With containers/containers.conf as suggested here (But I removed host-gateway) :

[network]
default_rootless_network_cmd = "pasta"
pasta_options = ["-a", "10.0.2.0", "-n", "24", "-g", "10.0.2.2", "--dns-forward", "10.0.2.3"]

Stopping and restarting the service systemctl --user restart nextcloud.service:

I tried adding the domains to /etc/hosts as some suggested, but no luck.
