SPROXY - No connection to ESR

Hi,

I am getting the ESR connection error to SPROXY to the PI 7.4 ( Java stack) from ECC 6.0 EHP7.

Below reports are giving error as well.

1.SPROX_CHECK_IFR_ADDRESS

cannot determine repository version

2.SPROX_CHECK_IFR_RESPONSE

Requested repository is down

SAP_SPROX_ESR connection test is working and destination type is G

a) Should I have check anything on the PI 7.4 side.

b) Should I check LCRSAPRFC connection for the ECC 6.0 EHP7 and PI 7.4 integration?

c) SLD hostname should be same in RZ70 and SLDAPICUST ?

Will appreciate any pointers for resolving the issue?

Thanks in advance
