FritzBox Call Monitor: Unable to open Phonebook

Configuration
1

I setup the FritzBox call monitor and it works well. Phone calls will be notice but unfortunately HA is not able to open my phonebook. Iā€™m using hass.io. When I tried same settings at native installation (not docker) my phonebook was read.

Can any one help?
