Dav5 and Nextcloud

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.
