After your browser refreshes, the browser might block access to the destination site and report that the site is using HTTP Strict Transport Security. This condition arises when you switch back to self-signed certificates. To clear the condition that is blocking access to the destination, you must clear the browsing data from the browser.
The system reverts to using the self-signed certificate from the server. As a result, the system prompts users to manually accept the self-signed certificate for their sessions.
