@Toky Raobelina When you add an RPG to the graph, the URL you provide in its configuration should be the same URL you would use to access that target NiFi's UI. You will then select whether to use RAW or HTTP protocols. With RAW (legacy format) your source NiFi will send data across port 8022. With HTTP protocol the Source NiFi will send data across port 8070. So you need to make sure with RAW that your source NiFi can communicate with port 8022 on the target NiFi. Based on what you shared, it sounds more like you have set up an entry point on the target NiFi to accept the data you want to send to it. On the target NiFi you will need to add an input port to your canvas. This port must be added at the root level to be used for S2S. BY root level, i mean it cannot be contained within a process group on the target NiFi. So on the canvas of your target NiFi, you will have a flow that looks similar to this: It may take a couple minutes for the input port to show up on the RPG located on the Source NiFi. You can always right click on the RPG and select "Refresh". On your Source NiFi you will have a flow similar to this: Once the input port is set to run and you have enabled transmission on your RPG, data should start flowing unless a firewall is blocking the connection on part 8022 as mentioned above.
