Our app connects to our backend via websocket from within a WKWebView. This works without any issues in iOS 14.
On iOS 15 Beta 5 the websocket connection fails initially, then succeeds after the app ran for 5 minutes or so.
I tried taking a RVI packet trace, but couldn't due to my iPad having the new style of UDID.
Any ideas how we can get this fixed before the release?

If this worked on iOS 14 but not is failing on iOS 15 this is grounds for a bug report. Please respond with your Feedback ID.

We are experiencing the same issue with the final iOS 15 build we installed yesterday (19A344). Will file a bug report as well.
Have been able to work around the issue temporarily by switching from the built-in web socket to cordova-plugin-advanced-websocket.
My feedbackID is: FB9631338 . I filed it against WebKit but this could be an issue deeper in the platform.
Thank you for opening this bug report. I see it internally. Would you be able to add a focused sample to your bug report?

Hi Matt,
I filed bug report FB9616225. Creating a focused sample will be quite time intensive, so this might take a while.
That said, I noticed that it manages to connect consistently after between 1 and 2 minutes. Meaning: I launch the app, websocket connection fails. With the app in the foreground, I wait 1 minute and it is still offline, but then it manages to connect before a second minute passes.
Maybe that provides a useful hint?
Thank you, Michi
