SAP Analytics Cloud to SAP BW Live Connection Preflight Error: No 'Access-Control-Allow-Origin'

Hi Experts,

I am trying for so long now to set up the BW Live Connection to SAC and somehow somethings prevents it...

I implemented the steps as in the following blog: and the sap help:, but still I get the error:

When I call Url of the BW Server: host:port (of bw Server)/sap/bw/ina/GetServerInfo?sap-client=001 it gives me the right headers, but I cannot understand why SAC still doesn't connect. The SSL Certificates are also all green.

I also have noticed that in the RZ10, I have created the Parameter:icm/HTTP/mod_0 and has given the directory where the CORS_REWRITE.TXT is located. However, when I try to check this Parameter in RZ11 and display its actual value, it shows me that the value of Parameter:icm/HTTP/mod_0 = PREFIX=/ without the other directory of the CORS_REWRITE.TXT file. Do you think it has something to do with this setting or perhaps something is still missing?
