Hi,
Thank you for your reply.
I asked to network administrator of my company, His reply was that the proxy server is appliance and maybe support TLS1.x.
So, I tested my env with TLS testing tool.
Below Test shows “Your client is using TLS 1.3, the most modern version of the encryption protocol.”, so I concider that the proxy server is also supporting TLS 1.2.

On the other hand, I tried to your test code at here.
$ node -v
v10.4.1
$ node test.js
error: null
statusCode: 200
body: {"ok":true}
It works, and there’s no problem with electron…?
