Hello,
The ICM_HTTP_CONNECTION_FAILED indicates that the SAP was acting as the HTTP client, and that the ICM could not connect to the target server.
The settings mentioned in this blog could be the root cause, but they are not the only possible root case.
Checking the entries written to the dev_icm trace file right after performing a connection test can reveal the other possible root causes.
For example:
1) "hostname unknown" -> DNS issue;
2) "connection refused" -> network issue; something at the network blocking the connection (firewall?); details of the target server are incorrect (hostname, port).

Hi Isaías,
When you have maintain details like mentioned in this blog, you did not get any issues like,
"hostname unknown" -> DNS issue.
Thanks

Hello Jana,
And what if there is no proxy involved? 😉

Hi Isaías,
To use Web services clients for external communication, you have to configure the global HTTP proxy settings. These global settings affect all Web services that are deployed on the server.
Thanks

In this case, maybe the title of your blog could be adjusted?
And even so, the errors I mentioned could still occur, even if the proxy settings are correct (a firewall could be blocking the connection from SAP to the proxy; SAP would still use DNS resolution to connect to the proxy, if a hostname is defined instead of the IP address of the proxy).
Cheers!
