This is probably happening because the site you are trying to reach is redirecting to an authentication server that is not configured to open in IE mode. You can try opening the site in standalone IE11 with Developer Tools open to see the identity of the authentication server.

The solution is to then configure the authentication server in your EMIE site list as “neutral”, like this:

<site url="login.contoso.com">

        <compat-mode>default</compat-mode>

        <open-in>Neutral</open-in>

    </site>
