“Connection refused” means nothing is listening at that host:port

or try without node-to-node encryption and enable later

Hi @kanamani92 !

–node-to-node-encryption on

Node-to-node encryption is not available in Community Edition.

Reference: Enterprise Edition vs. Community Edition vs. Couchbase Capella

–ip-family ipv6-only

Same for IPv6 (i think?) but I’m having a harder time finding a reference more authoritative than this forum post: Ipv6 support in community edition

I suspect couchbase-cli is attempting to connect to the server via an IPv6 address, but gets no response because Community Edition does not bind to IPv6 addresses.
