Our Hysteria2 connections died about 60 seconds into every upload speed test. DNS kept working, web traffic didn't. The cause was a QUIC flow-control stall in the Hysteria server. We fixed it with about 37 lines of Go. 🧵

The fix: if a write to the target makes no progress for 10 s, close it and release the window. Lab: the official server never recovers, the patched one in 7.8 s. On a phone: 4 speed tests over 160 s, no stall. Live on our servers, no app update needed.

A speed-test server stops reading its upload but keeps the connection open. The unread data fills the connection's 20 MB flow-control window, so no stream can send anymore, not even new requests. UDP isn't flow-controlled, so everything looked healthy.

A great technical challenge deserves a real test. Thanks to @launchgatecheck on DEV, we tested Colitu's VPN verification, improved tunnel checks, network recovery and DNS routing, and shipped the fixes. Full research: lab.colitu.com/research/rou...

A VPN can say “connected” while traffic is dead. Colitu Adaptive Connect 2.0 uses real-traffic checks, network-aware failover and a spare route. In one controlled 60-minute test: 741/750 probes succeeded. What worked and failed: docs.colitu.com/en/adaptive-...
