I've had Action Cable feeding information to signed-in users in my application for many moons, but recently my main development computer has had a problem.
In all my environments, Production and Staging, the Action Cable functionality feeds the info correctly to other computers like my phone, backup computer, and my buddy's computer, but my computer doesn't get anything.
The server logs look fine, they send the Action Cable messages, but my computer doesn't receive them. I'd give you more information but I have no idea what would help for this. I restarted my computer and turning my local server off, still nothing. The local environment works fine though.
