Describe the bug

axios or a used library produces this exception on some failed web requests, causing an application crash

To Reproduce

Hard to say, but this is my axios config:

httpAgent: new HttpProxyAgent(this.proxy),
httpsAgent: new HttpsProxyAgent(this.proxy),
proxy: false,

Make a request using a http proxy that ends up failing. (I know its a bug because sometimes a simple request retry fixes the issue)

Expected behavior

Axios returns the request properly

Environment

• Axios Version 0.21.0
• Adapter http
• Node.js Version v12.16.1
• OS: [e.g. iOS 12.1.0, OSX 10.13.4]
• Additional Library Versions [e.g. React 16.7, React Native 0.58.0]
