Anyone here have experience with getting mutual TLS authentication working with an Elixir HTTP client?I have a CA file, certificate, and private key that work in a few other contexts with the request am trying to make:
In Postman, using the built-in “Certificates” feature
Mint times out on connect/4 and HTTPoison sends the request, which the server rejects.The relevant information I can extract from the 400 response that HTTPoison gets me is “400 The SSL certificate error”—not very helpful. I’ve reached out to the support team for the API I am working with, but I was hoping you folks might have some insight in the interim.
Thanks for the tip, @tangui—I’ll have a go with verbose :httpc and report back.
The cert I’m testing with is a Let’s Encrypt certificate generated with certbot, so I think I’m okay as far as having a known CA, especially given the fact that the request works using other HTTP tools, e.g. curl.
