ICM_HTTP_SERVICE_UNAVAILABLE when testing connection to a HTTPS server

[Former Member]

Hello SAP gurus!

I have created a RFC connection to a wsdl server using the SOAMANAGER, which is on the secured connection (https). SAP cryptographic library is installed, in ICM I see the both services green (active). And still when I try to test my RFC connection in SM59 I'll get ICM_HTTP_SERVICE_UNAVAILABLE.

How come? When my HTTP SERVICE (as seen in TA smicm) is on and active? 😮

Any hints?

Thanks for help in advance.

Cheers!

Solved. Connectivity problem on the proxy. Can't tell what exactly it was, since I'm not in the infrastructure department.

Check if AS host and gateway details are correctly maintained and also gateway service is up n running.

Gateway service is maintained somewhere in SICF?

Check Hostname that you have set in RFC definition. Probably Hostname isn't mapped in your server host definitions.

You need to add the Hostname definitions (you can try also with IP address, but if you use SSL the hostname in RFC definition and in Server Certificate must be equal).

Hostname isn't mapped in your server host definitions? You mean something like DNS? The hostname of the https server is translated to IP by the way...

Yes exactly.

This is a connectivity issue, then check for Destination Hostname (try a ping) and check if Destination Hostname&Port is reachable from your server (networking & firewall).

Well, the result is like this:

Ping the HTTPS server (hostname or IP address, both returned same results) with the terminal from the application server:

100% packet loss.

The OS is openSUSE and the proxy setting is set correctly (firefox sees the internet... it also can view the https server mentioned above)

Ping from SAP (with OS01) also 100% loss, though the general proxy setting is also set.

Well... You need to contact Firewall&Networking group to check if:

- There's connectivity to destination Server

- Destination Server Ports for Service are open (port that you have set in Sap RFC definition)

[Former Member]

It seems you're right. The application server can't see the server through the desired port. OK, I'll contact the network guys and then I'll post the results.

Until then thanks for help!
