Unable to start project on streaming server
I am trying out the Smart Data Streaming – Freezer Monitoring Tutorial
While running the streaming project I am getting the below error :
In the console it shows :
Failed call to:https://hdbhost:57398/RPC2 (Failed to read server's response: hdbhost)
Please help me to get this issue resolved.
Thanks and Regards,

The most common reason for a failed RPC call is that the port being used isn't open. In this case that would be port 57398. Each streaming project requires 3 ports which are the Command port, SQL port and Gateway port. By default these ports are allocated dynamically when the project is started. That works great for servers on an internal LAN where all ports are open.
Is your HANA server running on a cloud server with only limited ports open?
If so, then take a look at this blog post on how to specifically assign the ports to be used by the project: Specifying the Command Port to be used by a Smart Data Streaming Project
