SPROXY not working in application system

Question

Hello all,
I have been trying to make SPROXY work in my QAS ERP 2004 SPS23 system
for a few days now but I can not make it. I have
configured SPROXY in the past for my sandbox and DEV system with
success but I do not seem to have any luck in QAS.
My PI landscape consists of sandbox, developement, qa and production
systems. The version is PI 7.0 SPS21
My ERP landscape consists of the same 4 systems but in version 6.40 -
ERP 2004 SPS23
All non production systems use a central SLD that runs in the PI development
box (PID)
The error message I get is as follows:
When I run SPROXY in ERP QAS client 330, I get : "No connection to Integration
Builder (only local data visible)"
When I do Goto --> Integration Builder, I get the message "Integration
Builder address not maintained"
However, when I do Goto --> Connection Test, from the 4 reports I have
to run, two work and two do not work:
=>Check/maintain with report SPROX_CHECK_IFR_ADDRESS works and shows the correct address for Integration repository
=>Check with report SPROX_CHECK_HTTP_COMMUNICATION works
The other two reports
=>Check with report SPROX_CHECK_IFR_RESPONSE
==>Check with report SPROX_CHECK_IFR_CONNECTION
return: Integration builder data not undestood.
SLDCHECK runs fine: All green and invokes correct IE session with the correct SLD URL (central SLD)
SLDAPICUST shows the correct SLD (central)
SXMB_ADM --> Integration Engine Configuration shows the destination RFC
SAPIS_PIQ
which is defined in SM59 as type H and works fine
TCP RFCs LCRSAPRFC and SAPSLDAPI work
The corresponding JCos in Visual Administration look ok
I have registered the queues in SXMB_ADM and they registered ok .
The /sap/xi/engine service is active in both the application system and the PI  system (QAs and PIQ)
Finally the exchange profile settings in PIQ are fine as well
com.sap.aii.connect.repository.name : piqas.finance.local
com.sap.aii.connect.repository.httpport : 50000
com.sap.aii.connect.repository.contextRoot :rep
com.sap.aii.connect.integrationbuilder.startpage.url : rep/start/index.jsp
com.sap.aii.applicationsystem.serviceuser.name: PIAPPLUSER
and the password is set.
PIAPPLUSER is service user and is not locked.
I have tested SLDCHECK in PIQ and SLDAPICUST and they look ok as well.
Any other clues? Any way I can investigate further via checking logs
and traces to find out what is wrong?
The "Data not understood" message is not helping me much in determining
what is wrong
Many thanks
Andreas
