We have a similar issue starting iOS 15 and also Safari 15.x on Mac.  The error we are getting is "[Error] WebSocket connection to 'wss://xxx' failed: WebSocket is closed before the connection is established." (xxx is our site).

Simply disconnecting from WiFi then reconnecting seems to fix it, but reloading the website does not. Our customers also report that restarting their devices fixes it. I do not know how to force reproduction of this bug but it is definitely happening to many of our customers since iOS 15 and the latest version of Safari. Is this still being investigated by the webkit team?
