Timeout on Non-proxied DNS

Hello. I have an A record managed via Cloudflare, that I have set to Non-proxied, and pointing towards an external VPS that I wish to have serve http/s traffic, as well as be accessed via ssh nslookup shows the correct ip address, and I am able to use the subdomain set in the A record to ssh into the server. However, http/s traffic is timing out when trying to reach the server, which is preventing me from successfully getting my SSL certificates from acme If I set up Nginx to not require certificates, and ensure that port 80 is open, I still recieve a timeout when attempting to access the server via http Am I missing steps for managing simple DNS records with Cloudflare in an unproxied manner?

Write to R2 with ReadableStream

Im trying to write a ReadableStream to R2, however, I cannot pass a stream to the r2 .put without giving it a fixed size first, so I am piping an email objects stream to a FixedLengthStream as so:

let { readable, writeable } = new FixedLengthStream(message.rawSize);
message.raw.pipeTo(writeable);

let { readable, writeable } = new FixedLengthStream(message.rawSize);
message.raw.pipeTo(writeable);

and then saving it to R2 as follows:

await env.BUCKET_NAME.put(identifier, readable);

await env.BUCKET_NAME.put(identifier, readable);

Im seeing the entry identifier in my R2 bucket, however the content is empty. message.rawSize is showing the number of bytes I would expect. Am I using the stream pipes wrong? Thank you

workers-rs: Unable to get local issuer certificate

I'm attempting to use the reqwest library within my worker to contact a third-party api.

async fn test_reqwest() -> Result<String> {
    let resp = reqwest::get("https://workers.cloudflare.com").await.unwrap().await.unwrap();
    Ok(String::from(resp))
}

async fn test_reqwest() -> Result<String> {
    let resp = reqwest::get("https://workers.cloudflare.com").await.unwrap().await.unwrap();
    Ok(String::from(resp))
}

I am running the worker using wrangler dev When the request is made wrangler shows the following error:

workerd/jsg/util.c++:275: error: e = kj/compat/tls.c++:221: failed: TLS peer's certificate is not trusted; reason = unable to get local issuer certificate

The same happens if I use workers Fetch api:

async fn test_reqwest() -> Result<String> {
    let mut resp = Fetch::Url("https://httpbin.org/anything".parse().unwrap())
        .send()
        .await?;
    let txt = resp.text().await?;
    Ok(String::from(txt))
}

async fn test_reqwest() -> Result<String> {
    let mut resp = Fetch::Url("https://httpbin.org/anything".parse().unwrap())
        .send()
        .await?;
    let txt = resp.text().await?;
    Ok(String::from(txt))
}

Is there a feature / configuration change I need to make to allow the worker to access third party apis? Thank you.

LetsEncrypt through Cloudflare Proxy

Hello, Im trying to deploy a server who's URL is proxied via Cloudflare. I can ssh to it through the tunnel, however my LetsEncrypt is failing to register. I'm unsure what the best way to allow this through is, I have added the server to a cloudflare tunnel, added the http/s options in the zero access "public hostname" entry, and added a page rule to disable SSL on the .well-known/acme-challenge route, to no avail. What else should I try? Thank you
