It happens because you can't access crypto in the browser when running through http (insecure context). Note that this rule doesn't apply for http://localhost nor http://127.0.0.1.
And by your screenshot, you're accessing http://10.203.161.238.

In general, you probably should just treat Crypto as available only on secure contexts.

Possible solutions are:

• Run a local https server - you can use a self-signed certificate.
• Run it through a tunnel, like localtunnel, which gives you an https URL to access your app.
