+        If you're using a self-signed certificate and want to disable certificate verification, select Skip certificate
+        verification.

+    <p>
+        <b>Note</b> We recommend that you don't disable certificate verification because self-signed certificates are
+        inherently not secure. Read the next section for more information about why you would or wouldn't use
