Yeah this site is not useing a CMS so I cant go the plugin route. Nextcloud has some security built in where you can allow certin domains to use the embed. So far it seems to be an issue with an update that happened recently. My domain is still whitelisted in the conf file but the iframe is getting an error saying that the server hosting nextcloud won't allow the connection.

Meh. Gonna poke it after a bike ride. Need a break from my screen anyways.
