When I checked network log on my phabricator install, I was unable to find any web socket request like the one on this server. I have upgraded to last stable version and here my servers settings in aphlict.json
```lang=json
"servers": [
{
"type": "client",
"port": 22280,
"listen": "0.0.0.0",
"ssl.key": null,
"ssl.cert": null,
"ssl.chain": null
},
{
"type": "admin",
"port": 22281,
"listen": "127.0.0.1",
"ssl.key": null,
"ssl.cert": null,
"ssl.chain": null
}
],
```
