I wanted ro report a Problem with adding an account which is hosted on my own Baikal server. This may be just a server issue, but I suggest you may update the documentation if you find it appropriate.
Officially the Base-URL stated in your FAQ is
/dav.php/ (e.g. https://server.example/baikal/dav.php/)(https://www.davdroid.com/tested-with/baikal/)
It only finds my account however when I type the principal URL
When looking at the error log, it actually finds the principals path even when leaving out the
/dav.php/-part, but somehow reports an internal server error upon request of that site. If I type directly the principal-URL, it finds the services of my user and succeeds.

PS.: DavDroid is a great app and I enjoy using it otherwise.
