CalDAV and CardDAV not working via Mobile Connector

Hello!

I am on cPanel ver 116.0.10 with CCS Server Tools installed and working correctly. I am able to see and use the CalDAV calendar and CardDAV address book via both the Roundcube Webmail interface and third party clients such as Thunderbird.

Problem:

I am trying to use a popular CalDAV / CardDAV adapter for Android called DAVx⁵ . However, DAVx5 is not able to ask the server for the actual collections of the given user.

The setup seems to be completed correctly since the debug info shows the account with the detected service URLs. So the Base URL seems to be the right one. After getting the services back from the server using the Base URL in the service detection, DAVx5 needs to ask the server for the actual collections of the given user. And DAVx5 gets a timeout and couldn't reach the server when doing this.

Response from the DAVx⁵ Support Team:

Please note that desktop apps like TB are working differently internally than mobile clients. For example we use a REPORT method to query the capabilities of a server, while TB is doing it with PROPFIND. However both variants are a normal CalDAV/CardDAV way to discover collections and its properties on the server side. Both must be supported by any CalDAV/CardDAV server. So it can definitely be that a desktop client may be able to find resources on the server while the same Base URL does not work on mobile.

 

Question:

Is it the case that cPanel CCS does not support the REPORT method?

  Hey there!  I spoke with the CCS team and confirmed that REPORT is supported in our implementation.

  If the service is getting a timeout, could there be a firewall issue in the server-side?  You could always try temporarily disabling the firewall to check that.

  Glad to report that CalDAV and CardDAV are now working via CalDAV / CardDAV adapter for Android called DAVx⁵. This happened when my hosting provider fixed another issue with CCS - Calendar Delegation Not Working. Not sure if both issues are related, or this was a happy coincidence.

  As confirmed by cPRex, REPORT is supported by the CCS implementation within cPanel. See below Network capture from Thunderbird:

  It seems like it would be related - glad to hear it's working well now!
