Error: DEPTH_ZERO_SELF_SIGNED_CERT

[endejoli]

Hello,
I am getting DEPTH_ZERO_SELF_SIGNED_CERT error while using the browser.
Tried the options like process.env.NODE_TLS_REJECT_UNAUTHORIZED = 0 and rejectUnauthorized: false, but both did not work.

proxy /api requests to etcd on etcd.abc.com:443
etc-browser listening on port 8081

events.js:72
throw er; // Unhandled 'error' event
^

Here is how I am starting the node server,

!/bin/sh

set -e
export ETCDCTL_CA_FILE=ca-certificates.crt
export ETCDCTL_KEY_FILE=etcd.abc.com.key
export ETCDCTL_CERT_FILE=etcd.abc.com.crt
export ETCD_HOST=etcd.abc.com
export ETCD_PORT=443
export SERVER_PORT=8081
sudo node server.js
