In my case the server is HTTP/3 (QUIC). My server* also can also only process 1 request at a time. How do I limit the concurrent request count for the session? * actually, it's Google Cloud Storage, and it can only handle 1 request at a time per file, which applies if you're using chunked uploads to upload a large file.

Wild. Relaunching the app to queue up new requests is going to increase battery usage. Any chance this will be fixed in a later release of iOS?

The originally reported bug is still present in Version 14.2 (14C18). Sometimes the 'CrashPointNetworkListSource' error appears but usually not, usually the organizer just says "No Crash Logs". That's despite there being a crash on App Store Connect. (Unfortunately, due to a different bug, the crash feedback on App Store Connect provides next to no information, certainly nothing useful.)
