Network issues
A connection failure or a partition between nodes can result in a network error.
The R server should run on a different computer than the computer where Team Studio is installed. In the case of a network disconnection or partition between nodes, R Execute jobs are terminated on the Team Studio computer, and the jobs are also terminated on the R server side (which directly handles the R workers).
The following message can be displayed if the R server Java Virtual Machine (JVM) terminates. It can also be displayed if there is a firewall between the Team Studio node and the R server node that blocks access on the ports chosen before Team Studio and the R server were started.
After the administrator ensures that both Team Studio and the R server are working correctly, and that the network is up and the firewall is properly configured, you should be able to retry the flow.
Execution of 'R Execute-4' failed. Error details: Connection to R server lost while executing operator. Please have your administrator check your network connection and confirm that your R server is running.
