This

const impit = new Impit();

const resp = await impit.fetch('https://faq.interlink.or.jp/faq2/View/wcDisplayContent.aspx?sso_step=1&id=737');
console.log(await resp.text());

results in

[Error: impit error: The internal HTTP library has thrown an error:
reqwest::Error {
    kind: Request,
    source: hyper_util::client::legacy::Error(
        Connect,
        Custom {
            kind: Other,
            error: Os {
                code: 104,
                kind: ConnectionReset,

            },
        },
    ),
}] {
  code: 'GenericFailure'
}

while with

const impit = new Impit({
+    browser: 'firefox'
});

this results in

        },
    ),
}] {

The server only supports TLS1.2 - and only a set of considered-weak ciphersuites.

In case of firefox emulation, the server picks one of the "bogus" ciphers (our rustls fork only sends this ciphersuite in the ClientHello message, without having the actual implementation).

In case of "default" impit (no emulation), the server resets the connection after receiving the ClientHello message, likely due to no cipher overlap(?).

Hi. Did you manage to fix the problem?
