Hey Markus,

You're right - CalDav support was added in 2018. In order to check out anything that might be causing problems, I'd like to try an import on an environment that matches your versions. Could you let me know the following?

  1. Which version of Confluence you're on
  2. Which version of the Team Calendars app you have installed
  3. What database your are using (PostgreSQL, MySQL, etc) and which version if you happen to know

Hallo Daniel,


thanks a lot for Your help! My configuration is:


  1. Confluenceversion 6.15.6
  2. TEAM CALENDAR Version 6.0.50
  3. POSTGREsql Version  9.6.14


For more details please have a look at the CONFLUENCE.PDF 


Vielen Dank


Hi Daniel,

I guess, it is an issue of a wrong certificate:

root@postgresql ~# wget
--2020-07-07 08:59:48--
Resolving (
Connecting to (||:443... connected.
ERROR: The certificate of '' is not trusted.
ERROR: The certificate of '' hasn't got a known issuer.
root@postgresql ~#

Ah, a certificate error. Using wget will use your operating system's certificate store. In the video you show, the certificate's trust is coming from the browser.

It looks like you have an Encryption Everywhere DV signed certificate. You might need to install the intermediate certificate on the server you ran wget on. The intermediate certificates can be downloaded from DigiCert here:

You can use this quick gist to install the intermediate certificate on your server.

That should at least clear the error with wget. If you've installed Confluence with the .bin installer and not changed its JRE to use your system's java, you might also need to install the intermediate certificate to the JRE's keystore. We've got instructions for doing that here, and although the article mentions Jira, the same process applies to Confluence.

Since the steps are rather involved, I won't copy them all here. Please let me know if you get stuck at any point though, and I'll be happy to help!

Dear Daniel,

and I changed the CA in Java Runtime. But still the connection is refused; but now with wrong creds as issue .... ?? Still confused and waiting for any help!screen.jpg


I forgot to mention: of course the calendar exists and the credentials are correct; I can log in with any other client.
