• While trying to establish a connection between the Cloud Connector and the backend system,  the data is not reaching the backend system even though it is reaching the Cloud Connector.
• In the ljs_trace.log / scc_core.trc similar to the following error is captured:

2025-03-26 11:58:57,847 +0000#DEBUG#com.sap.core.connectivity.protocol.http.handlers.HttpLocationHeaderHandler#tunnel-client-14-1#123456789#Location header represents unknown host: a.b.c.com. The value of the header remains unchanged: https://a.b.c.com:<port number>/sap/bc/srt..

• Here the original host is used in the request (d.e.f.com), but in the response due to the redirect another address will be used. This can be seen under the location of the response:
