Server connection lost, when example.com is in HTTPS

[temikael]

Hi,

Until now, my üWave server runs well and I can access to it via HTTP.
Now, I want to secure my server and pass to HTTPS.

I already create a Let's Encrypt certificate.
After an upgrade of my example.com.conf file and a reboot of Apache, I try to access my website via HTTPS and I receive this error:

When I glance at the console, I have these two messages:

socket.js:211 Mixed Content: The page at 'https://example.com/' was loaded over HTTPS, but attempted to connect to the insecure WebSocket endpoint 'ws://example.com:6042/'. This request has been blocked; this endpoint must be available over WSS.

socket.js:211 Uncaught (in promise) DOMException: Failed to construct 'WebSocket': An insecure WebSocket connection may not be initiated from a page loaded over HTTPS.

This is my Apache VirtualHost for example.com:

        LogLevel warn
        ErrorLog ${APACHE_LOG_DIR}/example.com.error.log

        RewriteEngine on
        RewriteCond %{HTTP:UPGRADE} ^WebSocket$ [NC]
        RewriteCond %{HTTP:CONNECTION} ^Upgrade$ [NC]
	RewriteRule .* ws://example.com:6042%{REQUEST_URI} [P]

        # This is for normal requests
        ProxyPass / http://example.com:6041/
        ProxyPassReverse / http://example.com:6041/
</VirtualHost>

For your information, I neither change the configuration of the core nor the configuration of the web client.

What do I need to change to make üWave work when example.com is in HTTPS?

[goto-bus-stop]

Do you have a socketUrl: option set in the web client options?

createWebClient({
  socketUrl: 'wss://example.com/'
})

By default it should derive the socket URL from the current URL. Eg if you host on https://example.com, it will derive wss://example.com, or if you host on http://something, it will derive ws://something.

It works fine on Chromium-like browsers, but not on Firefox.

I have this message:
Firefox can't establish a connection to the server at wss://example.com.
