Handshake issue (cookie is correct)

[finalclass]

I have a problem connecting clouseau with couchdb. I'm sure the cookie is correctly set because I can connect and ping the couchdb from a different erl process with net_adm:ping('couchdb@127.0.0.1') but starting clouseau and refrashing a page in fauxton I have this:
