Terminal Proxy Setup and Timeout Fixes
Git, npm, and Docker each read proxy settings from different sources, so changing terminal variables may not fix docker pull. Confirm the local port first, then inspect each actual configuration source.Scenario insightsSlow Steam Downloads or High Discord Voice Latency? Clash Game Routing and UDP Settings
The Steam store, game-content downloads, Discord voice, and actual gameplay traffic are not one connection. Test them separately to determine whether you need domain rules, process rules, or TUN.Scenario insightsRouting Netflix, YouTube, and Disney+ with Clash
