Workarounds

Use Firefox or Chrome to load the server

Disable Develop / Experimental / NSURLSession WebSocket in Safari

Two thoughts here!

1. I'm not familiar with NSURLSession but we should try to figure out if we're doing something wrong here.
2. This is probably more of a Snowpack issue than an Astro one!

I was able to recreate. I can find almost no information about this bug online though, which is pretty bizarre.

[jasikpark]

Yeah, you can also replicate by enabling the experimental NSUrlSession flag in Safari on macOS Bug Sur

This appears to be a bug in Safari, they are not sending the right status code: websockets/ws#1922

Going to wait and see if we get more information on that.

[matthewp]

Did some more research and this is indeed a Safari bug. They are not sending the status code as part of the close frame. As this is a bug in an experimental feature that is disabled by default, I'm going to close.
