Nextcloud is available outside my network but it can't seem to connect to the internet

[MediJaster]

Hello everyone!
As the title says, my new nextcloud (from the official apps) install works perfectly for everything it can do offline, e.g. uploading and viewing files, creating other users etc. But right from the dashboard the first problem pops-up: the interface can't seem to look up weather information, and I can confirm this by viewing logs from nextcloud's settings:

Show : Weather API error log

https://api.met.no/weatherapi/locationforecast/2.0/compactAPI error : GuzzleHttp\Exception\ConnectException: cURL error 7: Failed to connect to api.met.no port 443: No route to host (see https://curl.haxx.se/libcurl/c/libcurl-errors.html)

Now, if the problem was limited to the weather widget not working, I could have peacefully lived without it, but I also cannot browse or install any third-party apps.

I don't really know where to start troubleshooting, I tried stopping and starting the container twice and I also confirmed TrueNAS is giving internet access to docker apps because I could use curl inside a plex container and it worked normally.

Thank you for taking the time to read this, Please ask for anything that would help investigate this and I'll do my best to provide it to you.
