When a user click on browser icon in 2.7 or 2.91, the URL forces HTTPS protocol. In 2.93 that is not the case. It remains http. Our load balancer does not allow http traffic so the user gets a time out in their browser. Hosted environments do not require site/server level SSL certificate binding and 2.93+ start pages still render with https links.
Download and install the latest version and patch, if applicable.
