We are in the process of transitioning from IE11 to the Edge browser.
Our company's Internet network is a closed network.
We have been issued a valid SSL certificate. Therefore, the main site is normally accessed through HTTPS.
The main site screen did not appear normally because there were resources and links that were loaded via HTTP from the main site.
So I allowed insecure content (mixed content) in Edge browser settings.
When we did that, the address bar at the top was showing a "Not secure" message.
We must remove the "not secure" sign.
For some reason, it is not possible to change all linked resources to HTTPS.
I tried various settings in the registry referring to MS Docs, but I couldn't find the setting.
When using IE compatibility mode, the "Not secure" message was not displayed,
I don't want to use IE compatibility mode.
In the current state, there is no way to suppress the "not secure" message with registry settings or other settings.
Ask if there is. Thanks for reading.
