Websocket issues

As all other topics I've found from 2015 I have the same issue.

I am running good ol' apache as proxy, and configuration is:

1.  ProxyRequests off

2.        SSLProxyEngine on

3.        ProxyPass /phpmyadmin !

4.        ProxyPass /phpMyAdmin !

5.        ProxyPass /webmail !

6.        ProxyPass /roundcube !

7.        ProxyPass   /app/subscriptions ws://tc.morry.io:8111/app/subscriptions

8.        ProxyPassReverse    /app/subscriptions ws:/tc.morry.io:8111/app/subscriptions

Configuration is following:

<Connector port="8111" protocol="org.apache.coyote.http11.Http11NioProtocol"
connectionTimeout="60000"
useBodyEncodingForURI="true"
socket.txBufSize="64000"
socket.rxBufSize="64000"
tcpNoDelay="1"
proxyName="tc.morry.io"
proxyPort="443"
secure="true" scheme="https"
/>

As you can see I am using Nio protocol which should enable websockets. This is fresh instalation. I know I can use as is and hide notification, but my OCD doesn't allow me to.

I am running debian 10 buster

Thank you
