I am trying to run the Kafak Source Connector. When I start it using the connect-standalone.sh command from the quickstart documentation, I can see from logs that the bootstrapping of the Couchbase cluster nodes is successful, but then it trying to open a connection to CB on port 11210 and fails with below message and just repeats this failure continuously for all four nodes. I have verified that there is no firewall rule preventing the connection and the port is accessible from the server where I am running the Kafka Connector and they are on the same domain.
What else can cause this error? Do you have any troubleshooting suggestions?
INFO Connect attempt to <host>/10.249.176.27:11210 failed Could not open DCP Connection: Failed in the OPEN step, response status is 0x0024 (No access / insufficient permissions)
