Hey @theking003ks 
Welcome to the community.
Do post what troubleshooting you have done till now, it helps others to provide better help.
Also, instead of using an existing thread, try creating a new thread in appropriate section. (Unless your problem is exactly the same, which in this case it doesn’t look to be the case)
From what I see you are trying to access localhost over TLS (https) and most likely you do not have the certificates setup on your server. Try accessing your server over http, and things should work fine: http://localhost:4000
Assuming this is a plain vanilla test node server, highly likely https isn’t setup.
