(Re)connect not reliable on iOS 16

[Minnozz]

I have installed https://latest.glowing-bear.org as an application on my iPhone home screen. When I open the application, Glowing Bear won't automatically (re)connect since upgrading to iOS 16. Tapping the Connect button or the reconnect banner works, but sometimes this results in a double connection (messages I post appear twice in the chat history).

Hm, I can connect fine with iOS 16 but autoconnect doesn't work for me either. And after disconnecting I always see a connection error (even though it connected fine and worked fine). Can someone with a mac help out by getting the console output from the phone? Maybe this even reproduces on the new macOS as well?

The experimental WebKit feature NSURLSession WebSocket seems to be the cause. (Re)connecting works again when I set the toggle to off.

I believe Apple changed the default to on in iOS 16.

The feature flag is no longer present in iOS 17, so disabling it as a workaround is nice longer an option.

I've decided to put my weechat relay behind an Apache reverse proxy. Apache is able to handle the NSURLSession WebSocket requests from iOS where the weechat websocket implementation is not.
