Trying to use the caldav integration with NextCloud installed as an App on TrueNas Scale. I can access this cal from other apps besides HA (e.g. Thunderbird email client). This was working fine when I was using TrueNas Core and NextCloud as a Jail/plugin. I am laso reaching out to the truenas apps people because frankly I am not sure which side the root cause is coming from. Error to follow.
