Hi Dan,

I'm getting this a lot too with a fresh 11.3 install - if you get to the bottom of it I'd be keen to know what you find.

Thanks!

I have been digging into this for a while now. The alert windows pops every 100 seconds. It looks like this is a websocket timeout setting on our proxy server. We are looking into increasing that timeout.

We finally fixed this issue. We had a Cloudflare engineer adjust our proxy_read_timeout setting from 100 seconds to 900 seconds. That gives us at least 15 minutes before a timeout alert.
