Frontend serving from apache reverse proxy on subPath connection to api error - ver 1.41.0

[danieletas]

I'm trying to setup zigbee2mqtt serving from subpath using reverse proxy apache
I can serve frontend static content but no data are exchange with api node backend

in configuration.yaml frontend section:

frontend:
  host: 0.0.0.0
  port: 8080
  base_url: /zigbee2mqtt

I try several apache2 configurations, latest is:

<LocationMatch /zigbee2mqtt/api$>
	RewriteEngine On
	RewriteCond %{HTTP:Upgrade} websocket [NC]
	RewriteCond %{HTTP:Connection} upgrade [NC]
	RewriteRule /(.*) "ws://localhost:8080" [P,L]
</LocationMatch>



<Location /zigbee2mqtt/>
        RewriteEngine On
        RewriteCond %{HTTP:Upgrade} websocket [NC]
        RewriteCond %{HTTP:Connection} upgrade [NC]
        RewriteRule ^/zigbee2mqtt/api$ "ws://localhost:8080/api" [P]
        AddOutputFilterByType INFLATE;SUBSTITUTE;DEFLATE text/html
        AddOutputFilterByType INFLATE;SUBSTITUTE;DEFLATE text/css
        AddOutputFilterByType INFLATE;SUBSTITUTE;DEFLATE application/javascript

        ProxyPass http://localhost:8080/
        ProxyPassReverse http://localhost:8080/
</Location>

Request to websocket result failed
