I have same issue...
For some of the blobs i get this message:
WARNING the cache artifact for d6a63eff4c6deb9e was too large to upload within the timeout
WARNING the cache artifact for fb6dc9f4fa1e53b2 was too large to upload within the timeout
WARNING the cache artifact for 12a78c114ce555d8 was too large to upload within the timeout

AWS setup with Lambda behind ELB with cert and S3 as storage
The setup works for most of the blob, but some peek some limit and are not stored....

It looks like the timeout warning comes from the vercel/turborepo client. The timeout for the APIClient that uploads artifacts is set to 200 seconds:

https://github.com/vercel/turborepo/blob/7fb5b21fe3034c29affef8e35a8c90ee75c0cb67/crates/turborepo-cache/src/http.rs#L333-L339

        let api_client = APIClient::new(
            format!("http://localhost:{}", port),
            Some(Duration::from_secs(200)),
            None,
            "2.0.0",
            true,
        )?;
