The quic.nginx.org interop test was disabled due to TLS alert 112 errors. The known build error report shows 0 hits in the past 30+ days, indicating the external server issue has been resolved.

Filed new outerloop failure in #124602 otherwise it seems all is clear (ie. the rest is unrelated). |

The quic.nginx.org QUIC endpoint is timing out again from Helix CI machines, causing 100% failure rate on Public_Interop_ExactVersion_BufferContent_Success since Feb 21. The test was re-enabled in dotnet#124591 on Feb 19 but the external server became unreachable again 2 days later. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

The quic.nginx.org QUIC/HTTP3 interop test URI was re-enabled in #124591 (merged Feb 19), but the external server's QUIC endpoint became unreachable again starting Feb 21, causing **100% failure rate** (26 failures, 0 passes) on `Public_Interop_ExactVersion_BufferContent_Success` across all platforms. ### Analysis - **Error**: `Connection handshake was canceled due to the configured timeout of 00:00:10 seconds elapsing. (quic.nginx.org:443)` wrapping `QuicException` - **Scope**: Only the `quic.nginx.org` URI is affected; the `cloudflare-quic.com` URI passes fine - **Not a code regression**: The server responds to HTTP/1.1 requests normally, but its QUIC/UDP endpoint is not responding from Helix CI machines - **History**: This is the same class of external server issues that led to the original disablement in #120257 ### Example console log https://helixr1107v0xdcypoyl9e7f.blob.core.windows.net/dotnet-runtime-refs-heads-main-af729cf491f8439bab/System.Net.Http.Functional.Tests/3/console.e4a06694.log?helixlogtype=result ### Change Remove `quic.nginx.org` from the list of test uris permanently, as it is simply too unreliable to use in our CI. --------- Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
