Connection b/w SCC and on-premise system

Hi All,

I went through almost all the tutorials that are present in SCN for calling an Function module from on-premise system through cloud. So far i have failed to do so, In all the tutorials they say to install cloud connector and then create a small servlet class, deploy in HCP and run.

My question is do we need to configure anything on on-premise system so that the cloud connector can actually talk to on-premise SAP system so that the data transfer takes place?

I have installed cloud connector -->Access control added my onpremise system (shows green state), i have added resources (shows green state), also configured destinations in HCP, when i test connection it says connection successful, but when i run a simple application through HCP it give me error. Attached is the logs.

Please let me know what i am supposed to do for this.

Regards,

Alen Dsouza

    Hi Alen,

    the tunnel for the "data" connections cannot be opened:

    Connecting to address connectivitytunnel.hanatrial.ondemand.com/155.56.219.27:443. No proxy is used.|

    Successfully connected channel [id: 0x2bbf3aa8, /172.16.24.63:56352 => connectivitytunnel.hanatrial.ondemand.com/155.56.219.27:443]. Triggering tunnel handshake...|

    Sending handshake request: DefaultFullHttpRequest(decodeResult: success, version: HTTP/1.1, content: UnpooledHeapByteBuf(ridx: 0, widx: 0, cap: 0))

    Tunnel handshake failed! Closing the tunnel channel immediately

    Unexpected exception while establishing tunnel connection for tunnel: account:///p15908172trial java.nio.channels.ClosedChannelException|

    The "notification" connection however seems to be ok. (Which explains, why a "test connection" is successful.)

    Can it be a similar problem as this one: Cannot open tunnel...? Your firewall allows outgoing connections to connectivitycertsigning.hanatrial.ondemand.com and to connectivitynotification.hanatrial.ondemand.com, but not to connectivitytunnel.hanatrial.ondemand.com?!

    Let your network guys check this. Also noteworthy is: the unexpected exception comes exactly 10s after the start of the handshake request. Perhaps some firewall connect timeout?

    Best Regards, Ulrich
