Difference between the V4 cloud vs the V3 cloud with webservices

This morning I was testing some webservices on the v4 cloud and encountered some errors. At first I thought I made a mistake, but it seems their are differences in behaviour between the V4 and the V3 cloud. I created a new test project in SOAPUI and as always I copied the URL https://someURL/ws-doc/someWebservice?wsdl in SOAPUI. But it suddenly gives me the following error:

Error loading [https://someURL/ws-doc/someWebservice?wsdl]: java.lang.Exception: Failed to load url; https://someURL/ws-doc/someWebservice?wsdl, 0 - 

Since we have the same webservice on multiple environments I tested the other environments. On V3 environments they all loaded without a problem and failed on all the V4 environments. I then did a manual import of the wsdl and tried to consume the webservice. On the V4 cloud they all fail with the following error:

Error getting response,javax.ssl.SSL HandshakeException:Received fatal alert:handshake_failure

But on the V3 cloud all just works.

I did found this post on the forum recently: https://forum.mendixcloud.com/link/questions/87697

So it seems I am not the only one having problems with the V4 cloud. Any pointers someone what is happening here. Did I miss something in the documentation?
