Describe the bug

Getting weird error messages when passing a proxy into an Axios request. I've tried to add a proxy parameter to the following GET request and I get a 501 error code and when I then add a protocol parameter to the proxy object I get an openssl error

Note that I don't have any of these issues when using the library axios-https-proxy-fix, https://www.npmjs.com/package/axios-https-proxy-fix

To Reproduce

axios
    .get(prod, {
        proxy: {
            host: proxy.host,
            port: proxy.port,
            auth: {
                username: proxy.userName,
                password: proxy.password,
            },
        }
    })

Then I tried adding protocol to the proxy object, like so:

axios
    .get(prod, {
        proxy: {
            protocol: "https",
            host: proxy.host,
            port: proxy.port,
            auth: {
                username: proxy.userName,
                password: proxy.password,
            },
        }
    })

Error:

write EPROTO 17828:error:1408F10B:SSL routines:ssl3_get_record:wrong version number:c:\ws\deps\openssl\openssl\ssl\record\ssl3_record.c:332:

Expected behavior

No 501 and no openssl issues. Should get a 200 response.

Environment

• Axios Version 0.21.0
• Node.js Version 12.17
