CalDAV/CardDAV redirects SSL to port 80.

Postby nakedhitman » Sat Jan 17, 2015 10:33 am

I am using Nginx as a reverse-proxy in front of my Zimbra (8.5 community) server. When I connect to my server, the connection fails with an SSL error. It appears that something in the Zimbra DAV config is redirecting connections to port 80, which does not work for SSL. This issue affects multiple Android DAV sync clients. Full details and server config can be found at
