wcf service doesn't work with SOAPUI - create sequence fails - wcf

Question

I have build a wcf-service (vb.Net with VisualStudio2017) that works well with a testclient, and wcfstorm. SOAPUI can load the wsdl, but when sending a request, it fails with "a:ActionNotSupported"
My Service uses WsHttpbinding, no authentification, no security, with sessions and reliable messaging.
Messagetracing shows that my TestClient succeds with using
< CreateSequence xmlns="http://schemas.xmlsoap.org/ws/2005/02/rm">
where as SOAPUI fails with using
< wsa:Action>http://docs.oasis-open.org/ws-rx/wsrm/200702/CreateSequence< /wsa:Action>
My Questions:
How can i configure my Service to understand/accept the second schema?
I'm a bit puzzled, from what i understand it should already speak SOAP 1.2
How can i get SOAPUI to use a different schema? - or configure the request so it'll work?

While your error is in German and Google likely made a mess of translating it, it states
The action http://docs.oasis-open.org/ws-rx/wsrm/200702/CreateSequence is not supported by this endpoint. This endpoint only processes messages that meet the February 2005 WS-ReliableMessaging specification.
The suggested fix to test that it is causing the problem is to disable reliableBinding like this:
<wsHttpBinding>
<binding name="reliableBinding">
<reliableSession ordered="true" enabled="false" />
<security mode="None">
<message clientCredentialType="None" />
</security>
</binding>
</wsHttpBinding>
If that works you might try re-enabling it then in SOAP-UI you can enable WS-ReliableMessaging following this article Using WS-Reliable messaging
Update:
For a little more info on what SOAP-UI might support albeit they're discussing an older version see WCF services testing with SOAP-UI
If all else fails, I'd suggest posting in their forum/community
