Hey@feadrick, the ChannelUrl is used for SignalR communications. This was the api url, but it's now being split into it's own project (https://github.com/Resgrid/Core/tree/master/Web/Resgrid.Web.Eventing) to allow for better control of multi server router, seeming it uses web sockets it needs have sticky routing whereas the API and Web projects should be load balanced differently.

At the moment that is not in the built release package, if you build the latest source you can deploy it as ASP.Net Core web app to Linux or Windows. I'm working publishing a docker image for it as well shortly. When you deploy that website it's the location you'll use for the ChannelUrl.
