2197601 - Web Dispatcher "-checkconfig" fails when SSL is used for the metadata exchange with the Message Server

Symptom

The metadata exchange of the Web Dispatcher was configured to use HTTPS when communicating with the Message Server, either by setting the parameter:

wdisp/server_info_protocol = https

Or by setting the arguments "MSSPORT=<Message Server HTTPS port>" and "CONFIG_PROTOCOL=https" to the wdisp/system_<xx> parameter(s).

After that, executing "sapwebdisp pf=<path to profile> -checkconfig" raises one of the following errors:
