Are you making HTTP requests to an HTTPS server?

I had the same error

[SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:590)

Problem was that I was trying to access the notebook through http when I should have been trying with https. Same as what @minrk was suggesting in the first response to this post.

The real issue is that http isn’t redirecting to https automatically

It’s solved now. It’s just about proceeding to enter a password. https:// works.

Having the error. Connecting to HTTP. But connecting through a corporate proxy. Perhaps thats it.

That was it for me. My HTTPS_PROXY/https_proxy variables were set to “https😕/…” but should have been “http://…” because our corporate proxy doesn’t work with HTTPS.

The real issue is that http isn’t redirecting to https automatically

@gabefair You can use nginx to automatically redirect request to https. Here is how you can do it on ubuntu.

Install nginx: $ sudo apt -y install nginx

Check if nginx is active and running: $ sudo systemctl status nginx

If it is not enabled or running, execute these two commands:

$ sudo systemctl enable nginx
$ sudo systemctl start nginx

Navigate to below directory: $ cd /etc/nginx/sites-available

Edit the default file there, remove everything from it, and paste the below content:

server {
    listen 80;
    return 301 https://$host$request_uri;
}

Restart nginx: $ sudo systemctl restart nginx

Now any request coming over http(port 80) will be redirected to https(port 443) version.
