yes I have, but I have to find an alternative way to reaching my NAS since I can’t just do https://nas.mydomain.com:8443 as I am using a reverse proxy to make sure my subdomains point to specific ports on the NAS.
My current setup is:
I have a subdomain (contacts.mydomain.com) (443) which points to my DDNS mydomain.ddns.net. The DDNS points to my network, and the 443 reaches my NAS, goes through a reverse proxy and points to a specific port in the NAS (in this case 8008). I need to do this to make sure I have a recognised SSL certificate from my domain.
Again, this setup works (if I open a browser and go to contacts.mydomain.com, it asks me username and password, and I can access the cardDAV (contacts.mydomain.com is sending me to http://192.168.1.200:8008/addressbooks/users/alex/ via reverse proxy).
I understand that DAVx5 wants a diskstation.example.com:8443 type of address, but I can’t just appent the port number to my nas address, as it would not recognize the SSL cert
