@j-ed Thanks for the update!
Question: How can I connect to a server without login?
Is it possible to connect to a server anonymously, that means without login?
I have a Wordpress page with a Timely Calendar. Now I want to view the Events from this Website also in my Android calendar.
But when I try to create a connection in DAVdroid it rejects a connection entry without login and password.
What can I do to connect to this server?
I don’t think DAVdroid is the app you need in this case. CardDAV and CalDAV should be used to do a two way sync which requires some kind of authentication to be useful.
What you maybe need is our other app: ICSdroid. With this app you can subscribe to .ics-files and add them to you calendar.
this was what I was looking for.
