Did you configure .well-known URLs correctly? Error 405 means “method not supported”, which sounds likeeither your Web server is not configured correctly (GET, PUT, DELETE, PROPFIND, OPTIONS, REPORT methods have to be allowed), or your OwnCloud is not configured correctly.
Horde Internal Server Error
I think since update to 0.9.1.1 Davdroid shows me a similar error message. Since I use Horde I don’t think that’s a problem with the caldav server.
Before the update everything works fine an I didn’t change something at the server.
@user1: If you think that a server error message doesn’t indicate a server error, I think there’s nothing I can do for you.
Of course, if there is any plausible hint that the problem is on DAVdroid’s side, I’ll have a look at it.
I downgraded to version 0.9.0.4 and everything works fine.
Some details from the error Horde/sabredav error message:
HORDE [kronolith] SQL QUERY FAILED: SQLSTATE[HY000]: General error: 7 no connection to the server
Maybe you can give me a hint how to look further. Thanks.
@user1 Please ask in the Horde community because this is a Horde error message.
