ACME packages not allowed?

[wouser]

Hi all!

I recently setup a nextcloud snap on ubuntu, registered a domain name and wanted to use letsencrypt to get myself a nice SSL certificate through its build in lets-encrypt function.
However i ran into this error: http://XXXXX.nl/.well-known/acme-challenge/T_LUtymyAtw29gnQIFZRboGUtPGXyC9GndptOpP1bD4 with an type 'unauthorized'.

I also attempted an self-signed certificate which is working fine and allowing me to acces my nextcloud through my domain, only with an untrusted SSL certificate. Quite bothering me to be honest.

So i went to search for a solution to the problem. Attempted to use certbot on my unbuntu server, guessing it had to do with the nextcloud snap. However: Same error.

I started to figure it was my pfsense giving me these hiccups. Installed the ACME package to see if it could get an letsencrypt certificate: No succes. Tried with both webroot local folder and DNS manual (both staging certificates since it is for testing purposes).

I ran in the follow errors respectively:

Am i missing other settings in my router or is my domain name hoster blocking something??

Starting to feel its the latter…
