There are different ways to do WebSockets, and one of them is SignalR. In order for SignalR to work properly, you may need to update your web server configuration to enable WebSocket Protocol. If you’re in a web farm environment, you can’t just get a WebSocket to any one node. That wouldn’t work because that one node might not know about all the things that are going on elsewhere. So, in that case, you need to get Azure SignalR, which is a service of Microsoft. Even for a very large setup it should be less than $50/month. TipAzure SignalR Service ModeAs you're going through the setup process, you'll be prompted to select a Service Mode. Select "Default" when you're given this option. Once you’re signed up with Azure, you’ll come to Rock under Admin Tools > Settings > System Configuration and add your Endpoint and AccessKey.
