Unable to migrate Adressbooks from Apple calendarserver to radicale

[mc3]

macos 10.15 up to 13 seems unable to open addressbooks in radicale.
Same with thunderbird 102.

Addressbook has been exported as vcf with macos 10.15 contacts app.

server account configuration in contacts App is:

serveraddress: fqdn_of_server/ath_to_radicale_proxy
server path: user_name

Is this correct?

On IOS/IipadOS configuration works flawless, but contact groups are missing

Any advice welcome.

I attach a debug log from the initial dialog of a client, just after configuring the server credentials.
The client is a macOS/13.2.1 addressbook.
The discovery process seems to be successfull.
But again no vCards show up in the client.

Strange looks

What is going wrong here?
