Thank you for responding,
I was able to get this working with Elastic Cloud. This turned out to be a network issue, that should have been easy to sort. However, the misleading error message ( ‘couldnt get version’ ) and a heavy dose of tunnel-vision had me looking at the problem the wrong way.
keshav, as far as i know, couchbase is missing some functionality I need. One specific example is the percolator. Does couchbase offer something similar?
