(cluster_connector.cpp:192:void datastax::internal::core::ClusterConnector::on_connect(datastax::internal::core::ControlConnector *)): Unable to establish a control connection to host <IPv6 address> because of the following error: Underlying connection error: Received error response 'Invalid or unsupported protocol version (65); the lowest supported version is 3 and the greatest is 4' (0x0200000A)
when running as a systemd service.
This message is gone when I run the program that uses the cpp driver directly rather than as a non-systemd service. Does anyone know what I could try? systemd seems to be the culprit. Running on Ubuntu 18.04.3 LTS.
