"illegal configuration of HTTP/HTTPS in xdbconfig.xml"
*Cause: An attempt was made to update xdbconfig.xml when either
1) a value was specified for http2-port but not for
http2-protocol (or vice versa), OR
2) http-port and http2-port were set to the same value.
*Action: Specify values for both elements http2-port and http2-protocol,
AND set different values for http-port and http2-port.
