azimutt export <db_url> fails

[dsgraves]

I'm attempting to export a couchbase schema for a private instance of couchbase (enterprise 7.6.3). Steps taken:

From an ubuntu VM located on subnet of couchbase:

npm -g install azimutt
ubuntu@ip-10-51-2-190:~$ which azimutt
/home/ubuntu/.nvm/versions/node/v22.13.1/bin/azimutt

azimutt export couchbases://user:password@10.51.2.18

A tcpdump shows no traffic between .190 and .18

Suggestions?
