Node.js error with SSL UNABLE_TO_VERIFY_LEAF_SIGNATURE
javascript, node.js, openssl, ssl, windows
Solution
I'm using a package called "superagent" and getting the same error. After trying several potential fixes, I came across this one that works for me 100% of the time:
process.env.NODE_TLS_REJECT_UNAUTHORIZED = "0";
There's no need to do any requires or whatever : just add this to your code before your network calls and you're good to go.
Problem
System: Windows 7 NodeJS version: 0.10.2 WS module: ws, last version Error: ``` events.js:72 throw er; // Unhandled 'error' event ^ Error: UNABLE_TO_VERIFY_LEAF_SIGNATURE at SecurePair.
