I spent a lot of time troubleshooting an issue where Nginx will start silently dropping quic connections after config reloads if quic is enabled with reuseport and quic_bpf is set to on.
An issue about this bug has been open on the Nginx bugtracker since January of 2025, but the issue is not yet fixed, despite a fixing PR being open for almost as long.
I wrote this post on the Nginx community forum about this behavior, and also found this article explaining it in detail.
I spent quite some time troubleshooting this behavior, and it would be great if other people didn't spend a bunch of time troubleshooting an undocumented silent bug that mainline Nginx still hasn't fixed. I don't know if warnings about Nginx bugs belong in a config linter like Gixy, but figured I could at least make the suggestion.
