Sink is closed when using cbimport across the network to a Docker container

When using cbimport to import a dataset in a JSON file, we’re receiving the following error messages:

2018-06-29T15:37:09.148-04:00 ERRO: Timeout occurred (180 sec) on operation -- couchbase.(*Callbacks).handleError() at callbacks.go:117
2018-06-29T15:37:09.149-04:00 ERRO: The sink is closed -- jsondata.(*Parallelizer).Execute.func1() at source.go:191

Until we receive a “sink is closed” message.

This is running cbimport on a MacBook Pro across the network to a Docker image based Couchbase 5.1 3-node cluster. When we run the cbimport to a 5.1 Couchbase single-node cluster on the local machine, the import works to completion.

We’re working with DevOps to see if there’s anything they can see on the Docker/Network side, but wanted to check to see if you know of anything specific we should be looking for.

Thanks in advance, and please let me know if you need any further information.
