The client or server don't support a common SSL protocol version or cipher suite. If you are trying to connect a modern browser such as Microsoft Edge to HPe’s Integrated Lights Out 3 (iLO 3) management interface, you may receive the following error and be blocked from accessing the iLO webpage.
Edge will remember this setting on each subsequent visit.
Navigate to your iLO URL, select the three dots in the top right (Settings), and pick Reload in Internet Explorer mode from the menu. From the Allow sites to be reloaded in Internet Explorer mode drop-down, select Allow. To enable IE mode, launch edge and type edge://settings/defaultBrowser in the address bar.

UPDATE: Since writing this article in November it does not appear this fix works anymore.
