Thunderbird, Lightning and CalDAV, and CardDAV

[wrender]

Does anyone have CalDAV, and CardDAV working with Thunderbird? I am trying with Thunderbird 38.2.0, and Lightning Addon 4.0.2.1.

When I add a new calendar in Lightning, and choose "Network Location" -> "CalDAV" and put in the location "Direct URLs for Calendars" it adds the calendar, but when I try to add a calendar event it says:
Error code: MODIFICATION_FAILED
Status Code: 2147746065, The request cannot be processed.
Server Replied with 500

If I try and add the "Advanced Manual Settings" Server address in the location field it says "The calendar is momentarily not available" and it does not appear to function.

I have already open the related TCP ports. 2079, and 2080.

Hello

Do you notice any output to /usr/local/cpanel/logs/cpdavd_error_log when you receive the 500 error message in Thunderbird's Lighting Calendar?

Thank you.

I see these errors but not sure if they are related:

Application Bug: there is still content data waiting on the incoming socket and we ignored it!

I notice that activesync is a planned feature that cPanel is working on so I may just wait this out. I setup a dedicated Horde Webmail Edition server, and setup activesync, and have it just pulling IMAP from the cPanel server. The activesync from this dedicated Horde server is working great on my android phone, and Outlook 2016. Everything syncs great.

Hello

Internal case CPANEL-1934 is open to address an issue similar to what you have reported. Could you try using the "Synchronize Calendars" option in Thunderbird and see if shows your newly created event after you notice the error message?

Thank you.
