We noticed that websocket were broken with this config.
We believe that the translation from old config to new config in [this commit](130eb551a7 (diff-6f9b0c296a7ff789834c1414349f64f956f2b64df6e405fd45f62c6a11edad3fL34)) didn't translate it well.
We are actually wondering what does private stands for in this context.
With this change, we can confirm that wss works again as expected.
