I’m trying to install a very simple add-on on my Confluence Cloud but get the following error:
The add-on host returned HTTP response code 401 when we tried to contact it during installation. Please try again later or contact the add-on vendor.
GET /atlassian-connect.json 200 6.000 ms - 786 2017-05-08T13:12:35+0200 <warn> authentication.js:72 (sendError) Authentication verification error: 401 Could not find authentication data on request POST /installed?user_key=ff8080815bc92357015bc92388a60001 401 17.497 ms - 45
My add-on uses the ACT framework and is hosted on https.
