reqwest::Error { kind: Builder, source: Normal(ErrorStack([])) } in docker container

[DanielMauderer]

Environment

sentry = "0.36.0"
rust version: 1.83.0-nightly

Steps to Reproduce

I init sentry with this snippet below on my local machine it works without problems.

In my docker container however it panics.

I tried curl www.google.com and is succeeded so I have internet connection.

 let _guard = sentry::init((
        sentry_url.clone(),
        sentry::ClientOptions {
            release: sentry::release_name!(),
            ..Default::default()
        },
    ));

Expected Result

No panic and logging correctly to my sentry dashboard just like my local env.

Actual Result

stack trace:

I can't figure out why the builder failes with an empty ErrorStack.

Hi @DanielMauderer, thanks for reporting the issue.
Are you using rustlang/rust:nightly as the Docker image?
I'm unable to reproduce this with that image.

Hi,

was not home the past days. I fixed it today it was a certificates problem.

I saw a comment in the code: "This method fails if a TLS backend cannot be initialized". However I still would have expected an empty ErrorStack.

But I looks like this is a reqwest issue.

thanks for the reply. this issue can be closed.

Thank you for reporting that.
Maybe you could share how you fixed it so that other people that have the same problem can find a solution here :)
