Cryptic {:error, :closed} return from a POST

For anyone else who stumbles upon this issue, adding a simple retry (as suggested by yordis) has eliminated this issue for us.

{Tesla.Middleware.Retry, delay: 1000, max_retries: 5}

What does this error mean? Is it the remote closing of a TCP connection?

I am not sure but I would suggest using another adapter. I found some opened issues related to the topic benoitc/hackney#439 benoitc/hackney#630

What recourse do we have when this happens? Tesla states that it will already retry in most cases, but does this bubbling up imply that all retries failed?

You need to add Tesla.Middleware.Retry middleware, check Tesla.Middleware.Retry documentation to learn more about it.

Some documentation on this would be amazing; happy to put in a PR myself if we can get info on triggers and solutions.

Improvements are always welcome 💜
