   I redacted the server hostname and port with "http://redacted.com". Hopefully this is helpful.

   I fixed it by enabling the Share API (toggle "Allow apps to use the Share API" on at http://your-nextcloud.com/settings/admin/sharing).
   Found the solution in #2815 so I'll close this as a duplicate.
