so I installed couchdb on my VPS using snap, it only listened on 127.0.0.1 and this was not ok for me as It's not practical to ssh on a production environment, I would like it to listen on my external IP so I set in the /var/snap/couchdb/1/local.ini the following
[httpd]
bind_address = 0.0.0.0
however it still didn't work, using lsof -i -n -P | grep LISTEN
gave me the following which shows its still listening on the local host:
