TypeError: webCrypto is undefined

[MissingDLL]

I have installed the container via the basic exmaple. I have changed the environment variables from localhost to my servers ip. After that i could see the sign-up screen (email is not send out when adding but you can check for the activate code in the server log).
Wenn setting a password i do the the following error:
webCrypto is undefined

When checking the console logs it shows:

Uncaught (in promise) TypeError: webCrypto is undefined
    generateKey crypto.ts:43
    initialize account.ts:155
    signup app.ts:670
    _confirmPassword login-signup.ts:515

    handleEvent lit-html.js:1192
Promised response from onMessage listener went out of scope

Look at the same already answered issue here #723.

You need to host it over https so there is a security context.
