During maintenance of your Jive on-premise instance, when you change their maintenance URL from
https://<jive_community>/___sbsstatic___/setcookie.html to redirect it to the SSO login page, the page gets stuck on the loading screen. The issue remains unresolved even after restarting the Jive instance.
This occurs due to the Mixed Content errors on the
https://<jive_community>/___sbsstatic___/setcookie.html page. This will get resolved automatically upon the maintenance expiration or by manually disabling the maintenance mode.
