Bug that occurs on v15.0.1 and v15.0.0 only.

uname -a:
Linux tested 5.8.0-25-generic #26-Ubuntu SMP Thu Oct 15 10:30:38 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

What steps will reproduce the bug?

Any attempt to use proxy-agent for doing a proxy request...
Code example:

const axios = require('axios');
const ProxyAgent = require('proxy-agent');
const theAgent = new ProxyAgent('socks5://127.0.0.1:9050/');

axios.get('https://example.com', { agent: { http: theAgent, https: theAgent } }).then(response => {
  console.log(response.statusCode, response.headers);
}).catch(error => {
  if (error.response) {
    console.log(error.response.statusCode, error.response.headers);
  } else {
    console.log(error);
  }
});

How often does it reproduce? Is there a required condition?

No, not at all just using v15.

What is the expected behavior?

For the agent to work properly, and proxy the request as it should be like in any other versions of nodejs.

What do you see instead?

Connection times out, or something like that, and the request would normally fail going through.

Additional information

On top of that I'm getting frequent crashes when I'm sending many requests on nodejs v14.14.0
FATAL ERROR: v8::FromJust Maybe value is Nothing. .....* SOME RANDOM STUFF GOES HERE * 11: 0x7f806de50609 [/lib/x86_64-linux-gnu/libpthread.so.0] 12: 0x7f806dd75293 clone [/lib/x86_64-linux-gnu/libc.so.6] Aborted (core dumped)
I'm getting this error pretty frequently in v14 so there's that too.
