what happened to ws-conn-string

Community Support

I’m running into an issue with bokeh server behind nginx proxy. getting “websocket creation failed to url: ws:////ws”

From google it seems there used to be an server option ws-conn-string that can be used to change ws to wss but that doesn’t seem to be the case anymore. did that functionality move?

Hi,

The ws-conn-string parameter refers to the original Bokeh server, which has been completely deprecated since last year and in unsupported in any way.

The new server will automatically use ws/wss based on the connection type (http or https) reported by a proxy. You can find more information about deploying a Bokeh Server with SSL/Nginx here:

  Bokeh server — Bokeh 3.3.2 Documentation

The main point is to use the "--use-xheaders" option on the bokeh server, and then configure your proxy to forward the X-headers. Things will almost certainly work with other proxies (Apache, NodeJS) but I don't have the expertise to develop those sections. If you, a pull request to add additional example configurations to the documentation would certainly be appreciated.

Thanks,

Bryan

Thanks! --use-xheaders fixed it.
