OwnCloud returns error 500 and there are errors in the OwnCloud logs. I really doubt this is a DAVdroid problem.
http/1.1 411 Length Required
Since I updated to DAVdroid 1.0.9, I can’t upload new dates. I’m running Davical on nginx 1.2.1. Here’s the log: davical_http_411.log
Seems like davical (or nginx? but it works with nginx here) doesn’t like requests without
Content-Length. However, I don’t know why … can’t find anything in the RFCs about required Content-Length (vs streamed content).
Can you provide more information about your server (nginx version, PHP configuration, CalDAV server version etc.)?
Should be fixed with version 18.104.22.168.
