First things first, make sure your ISP’s device can be put into a bridge mode, or that you can get a modem instead, otherwise you’re going to be dealing with double NAT issues.

Yeah, trying an incognito window without the extensions would be the best place to start then, if you want to continue to use Firefox for it.

Even when you’re not using a reverse proxy, you’re still going to be streaming to that socket.

So I woild recomend that flag still and retest, because the only time I personally have seen that error is when the socket was closed to streaming and it fails to get returned data.
