Hi Johan, there is nothing special ... InfCloud = static files on the disk returned by a web server to your browser (where these are executed by JavaScript engine). And JavaScript has a lot of security constraints (e.g. CORS) that can be "fixed" only by returning proper HTTP headers from your Cal/CardDAV server. My tip is: Nginx does not processes the .htaccess file and/or there are missing CORS headers (previously present in your Apache config) ... check the console log. JM

But with a twist... As I can trace it, it seems that InfCloud requires a 204 response on OPTION queries. The other clients (CalDAV-Sync, DAVx5, vdirsyncer) want the 'normal' 200 response code. I can configure nginx to force return 204 but that will cause the other clients to stop updating. So I'm stuck here. Either InfCloud works, or all the other clients. Am I really the only one running (trying to run) a DAViCal with Nginx?

I use infcloud with davical with nginx without problem...
