Nextcloud / WebDAV error: Failed to connect to server. Likely a TLS issue, even though I enabled "Disable Certificate Checks".

Failed to connect to server. Please check your user name, password and the server address and retry.

This error shows up for both account types:

  • Nextcloud - OAuth flow happening in the browser is successful, but OpenTodoList app errors out
  • WebDAV - errors out

The endpoint I provided works perfectly fine in Super Productivity app.

Endpoint: https://owncloud.MYNICKNAME.net/remote.php/dav/files/Nowaker/
