@jianwu I have fixed the issue and I will publish this fix in next release.

[jianwu]

Thanks for the quick fix. This extension is excellent!

[Huachao]

@jianwu you can verify this feature in latest version 0.20.0

[jianwu]

I tried it. It seems a bit better. But as my proxy is https and the target server is http: so it throws another error:
Hostname/IP doesn't match certificate's altnames: "Host: XXXXXX. is not in the cert's altnames: DNS:XXXXXXX"

I did some research seems you need to add:

proxy.web(req, res, {
changeOrigin: true,
target: https://example.com:3000,
});

if you are using http-proxy or you can provide a setting: {rejectUnauthorized:false}

@jianwu can you try the latest version 0.20.1 to verify?

[jianwu]

I tried the latest 0.20.2, it still doesn't work. I used wireshark to inspect the network traffic. Seems even I put "https://" for the http.proxy setting, it still tries to connect with http protocol. With TLS handshake.So the connect got rejected, I got "read ECONNRESET" error

[Huachao]

@jianwu in your case, you are sending request to an HTTPS site, and your proxy is also in HTTPS protocol right, what's the port number of your proxy?

[jianwu]

My case, the proxy is in HTTPS and port number 8443, the target server is
http, port number is 8080.

I also get "ECONNRESET" at TLS handshake on https requests without proxy setup.

[Huachao]

@4nu81 can you provide your request if convenient?

[4nu81]

GET https://{{myhost}}/ HTTP/1.1

leads to:

write EPROTO 797870719880:error:100000f0:SSL routines:OPENSSL_internal:UNSUPPORTED_PROTOCOL:../../third_party/boringssl/src/ssl/handshake_client.cc:568:

The server we reach out for serves https with TLS handshake.

[Huachao]

@4nu81 It may be a bug related to the switch from OpenSSL to BoringSSL in electron which is the foundation of vscode.

I'm getting the same thing when trying an https request:

write EPROTO 1610660856:error:100000f0:SSL routines:OPENSSL_internal:UNSUPPORTED_PROTOCOL:../../third_party/boringssl/src/ssl/handshake_client.cc:568:
