Insomnia rest client error

Question

When I do a POST request I am getting this error. Error: connect ECONNREFUSED 127.0.0.1:3000. On the contrary, when I use postman it works.

This is the url: http://localhost:3000/users/sign_in

And this is my configuration:

JSON tab:

{"user": {"email": "user@nivelr.com", "password": "clave12345"}}

Headers:

Accept application/json
Content-Type application/json

Let's just hope this isn't a password you use else where – Dexter Aug 16 '19 at 09:16 — Dexter, Aug 16 '19 at 09:16

I'm the developer of Insomnia, and would like to let you know that this problem has been fixed in a recent release.

The app will now first attempt an IPv6 lookup (usually ::1), then fallback to an IPv4 lookup (usually 127.0.0.1) on error. This now aligns with the behavior of the curl command line tool.

You can download the latest version here for Mac, Windows, or Linux.

@gschier thanks for that - FYI I was having this issue with Insomnia v2021.2.0 on Windows Server 2016, but updating to v2021.2.1 fixed the issue. – ABVincita Mar 25 '21 at 02:36

I'm a little late here obviously, but if you've never figured it out, using http://[::1] instead of http://localhost solved this issue for me. It seems that some servers (in my case, Rust's Iron), when told to listen on localhost, interpret it as IPv6 ([::1]), hence the IPv4 address stops working.
