ActionCable WebSocket with Apache2 proxy

ws-with-apache2-proxy.conf

<VirtualHost *:80 *:443>
  # Domain
  ServerName servername.domain

  SSLEngine On
  SSLProxyEngine On
  # Path to SSL CRT file
  SSLCertificateFile /etc/apache2/ssl/apache.crt
  # Path to SSL KEY file
  SSLCertificateKeyFile /etc/apache2/ssl/apache.key

  ProxyRequests Off
  ProxyPreserveHost On

  <Location />
    ProxyPass http://0.0.0.0:3000/
    ProxyPassReverse http://0.0.0.0:3000/
  </Location>
  <Location /cable>
    ProxyPass ws://0.0.0.0:3000/cable
    ProxyPassReverse ws://0.0.0.0:3000/cale
  </Location>
</VirtualHost>

Doesn't work for me (((
I've got
"WebSocket connection to 'wss://site.domain/cable' failed: Connection closed before receiving a handshake response"

Can you help me? I've already broken my mind with it ((

<VirtualHost site.domain:*>
    ServerName site.domain

    SSLEngine on
    SSLProxyEngine on                           # make sure apache knows SSL is okay to proxy

    SSLCertificateFile /хххct.crt
    SSLCertificateKeyFile /ххct.key

    RequestHeader set X_FORWARDED_PROTO 'https'

    ProxyRequests Off
    ProxyPreserveHost On

  <Location />
    ProxyPass http://127.0.0.1:3001/
    ProxyPassReverse http://127.0.0.1:3001/
  </Location>
  <Location /cable>
    ProxyPass wss://127.0.0.1:3001/cable
    ProxyPassReverse wss://127.0.0.1:3001/cable
  </Location>
</VirtualHost>

I'm stuck (((((((

@ForeverYoung This code solved for me.

<VirtualHost *:80  *:443>
  ServerName api.mysite.com.br
  ServerAlias app.mysite.com.br

  DocumentRoot "/webapp/mysite/public"

  #SSLEngine On
  #SSLProxyEngine On

  ProxyRequests Off
  ProxyPreserveHost on

  <Location />
    ProxyPass http://0.0.0.0:3000/
    ProxyPassReverse http://0.0.0.0:3000/
  </Location>
 
 # ----------------------------------------
 # difference
 # host.com.br instead of 0.0.0.0:3000

    ProxyPass ws://mysite.com.br:3000/cable
    ProxyPassReverse ws://mysite.com.br:3000/cable
