Check https:// url for owncloud and use https by default for owncloud
Review Request #106543 - Created Sept. 23, 2012 and submitted
OwnCloud in Web Accounts won't accept https:// url for now, and for common free owncloud service, use fixedUrl with https:// may be a better solution. Check both http/https might be a better solution, but we can leave that to future I think.
https:// now works.
