We are testing Onlyoffice as self-hosted replacement of Google Suite and faced an issue with CalDav / Calendar.

  1. On the we changed
    “Custom domain name” in the “DNS Settings” to
  2. Go to
  3. Then edit Calendar → Export and Sync → Copied CalDAV URL
  4. Open it in browser, entered my email and password and asked for username and password again.
  5. Checked radicale.log inside onlyoffice-community-server container:

Also we tried to disable “Custom domain name”, in that case we were able to connect to the OnlyOffice calendar by CalDav, and got events. But, we were unable to create events in the Thunderbird and then synchronize it with OnlyOffice, radicale.log:

Hope that data will be enough to begin investigation.
