HTTP Sender - NiPConnect2: SiPeekPendConn failed error in SMICM

Hi guys,

at the moment we are upgrading to PI 7.11

therefore we copied our system to a new one.´, name it XX2

now we are testing an scenario using the new copy XX2. In this scenario the data is send via HTTP sender adapter directly to the ABAP Stack of the PI.

Unfortunately we receive no data in sxi_monitor and the sender gets an error like "the webservice you called is not available at the moment"

I looked at the trace of the ICM transaction smicm to get more information about the error.

But all I saw is this error

[Thr 2199294388560] *** ERROR => NiPConnect2: SiPeekPendConn failed for hdl 27 / sock 27
    (SI_ECONN_REFUSE/111; I4; ST; [nixxi.cpp    2823]
[Thr 2199294388560] *** WARNING => Connection request from (0/1/0) to host:, service: 58100 failed (NIECONN_
 {00020161} [icxxconn_mt.c 2321]

the ip and the port in this error message is not correct for this PI system XX2. Its the ip and the port of the old PI system, which is in upgrade at the moment.

It seems there are invalid configuration parameter somewhere, but I don´t know where.

Could anybody tell me where to correct the parameter of the PI pipeline?

Thanks in advance

Kind regards
