I’m looking for some support please.

I’ve got a Synology NAS running the current version of DSM (DSM 6.2.2-24922 Update 4). I’ve installed CardDAV server, and pointed DAVx5 on my android device to the server according to the exact instructions of https://www.davx5.com/tested-with/synology

The response is weird:

If I connect using http I get no response at all. If I connect using https I get a response, but only Calendar features show up, no CardDAV address book is found I can connect to ip:port for either http or https from the android browser, and there is a server there.

The log appears to report an authentication failure, but the password is being pre filled by a password manager on my phone. The same password manager I use to log in through my PC browser. And it sort of half works on https, so?

An example log:
