Dav5 and Nextcloud

Hi.
Yesterday I’ve connected Nextcloud with Cloudflare.
Today I’m trying to setup DAV5. Unfortunately it seems that there are no Candace services.
What I’m doing wrong? How can I fix it?

Thanks in advance for any help

As usual I recommend to

  • provide information about your environment and versions.
  • Install and activate the Calendar app.
  • check the Nextcloud log file.
  • read the user guide on this topic.
  • provide detailed information how you’ve set-up the app, what errors are displayed etc.
