Connecting iOS12 Calendar to ZuluCalDav

[Joel Stoner]

I have not seen this myself yet, but one of our customers using Zulu is reporting that they can connect iOS11 devices to the Zulu CalDav, but multiple iOS12 devices are giving the error “CalDAV account verification failed” when trying to connect. Is anyone else seeing this, or have any thoughts?

Hi Joel,

iOS 12 and Mojave require that CalDAV accounts connect over SSL, so when you make your account, enable SSL. Also, make sure your server is open on port 443. A default FileMaker Server install usually allows that anyway, but if you're implementing a network gateway, you'll have to make sure you have the proper port forwarding set up.
