Unhandled promise rejection (rejection id: 2): Error: connect EINVAL 0.0.31.182:443

I followed the instructions given and node fetch-submissions.js gives me the following:

(node:18346) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 2): Error: connect EINVAL 0.0.31.182:443 - Local (0.0.0.0:0)
(node:18346) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

host gives me:

$> host.leetcode.com

Pinging it:

$> ping leetcode.com

Solved by temporarily turning off proxy (it's not handled apparently):

http_proxy= https_proxy= node fetch-submissions.js
