capistrano: deploy gets stuck and doesn't print anything

Steps to reproduce

cap production deploy and that’s it, just gets stuck forever until I abort it

Expected behavior

Capistrano must to print a TimeOut error log or something else when it doesn’t connect to server

Actual behavior

When I run: cap production deploy it shows nothing, just keeps waiting But when I run: cap production deploy --trace it shows this:

** Invoke production (first_time)
** Execute production
** Invoke load:defaults (first_time)
** Execute load:defaults
** Invoke rbenv:validate (first_time)
** Execute rbenv:validate

Yes @anyelopetit please follow up with us when you track down what was causing the freeze. There may be something capistrano can do better in terms of error messaging.

My assumption is that rbenv:validate is the very first task that actually requires an SSH connection to the remote host, and that SSH connection is failing to open. You could try changing the connection timeout to see if that changes anything.

set :connection_timeout, 5

We probably can’t help you fix the reason for the timeout (that is likely due to a firewall between you and the remote host, or an incorrect port number). But we may be able to improve capistrano to provide better error messaging, or maybe a more reasonable default timeout so capistrano doesn’t appear to hang indefinitely.
