HCC failed to connect to trial HCP

[pavlo_denysyuk]

Hi experts,

I am trying to expose some of HANA XS ( on premise ) services to trial HANA Cloud Platform. I have installed Cloud Connector and went through official initial config . When I try to connect in status I see CONNECT_FAILED.

Hope I would get some remarks on how to fix it .

Here are some logs :

Thanks, Morten.

We have reinstalled HCC from dev to prod and got connection. Assuming JAVA version issue. While prod HCC installation JAVA was reinstalled.

Hi Pavlo

Are you certain that outbound connections to the internet through the firewall are allowed from the host, you installed SCC on? The prerequisites page lists three named hosts and their IP addresses, which must be reachable from your local SCC host. One of those (connectivitynotification.hanatrial.ondemand.com) appears in your log.

Regards,

Morten
