I'm trying to figure out how to configure HTTPS on 2.2.1.Final. I've done it on 2.1.0.Final and had it functioning. I used to put the following into standalone/configuration/keycloak-server.json

"connectionsHttpClient": {
    "default": {},
    "client-keystore": "${jboss.home.dir}/standalone/configuration/keycloak.jks",
    "client-keystore-password": "TPF-KCVM-KCKEYSTOREPASS",
    "client-key-password": "TPF-KCVM-KCKEYSTOREPASS"
},

Now I understand there is no more JSON file. I'm having issues getting the XML version running in standalone/configuration/standalone.xml.

I looked at https://keycloak.gitbooks.io/server-installation-and-configuration/content/v/2.2/topics/network/outgoing.html and now I've got this:

<spi name="connectionsHttpClient">
                <provider name="default" enabled="true"/>
                    <properties>
                        <property name="client-keystore" value="${jboss.home.dir}/standalone/configuration/keycloak.jks"/>
                        <property name="client-keystore-password" value="Test1234"/>
                        <property name="client-key-password" value="Test1234"/>
                    </properties>
            </spi>

And also:

                <spi name="truststore">
                        <provider name="file" enabled="true">
                                <properties>
                                        <property name="file" value="${jboss.home.dir}/standalone/configuration/keycloak.jks"/>
                                        <property name="password" value="Test1234"/>
                                        <property name="hostname-verification-policy" value="WILDCARD"/>
                                        <property name="disabled" value="false"/>
                                </properties>
                        </provider>
                </spi>

However, when I start Keycloak I get this error:

Did I do it wrong?
