fix: resolve HTTP 502 — clean conflicting Nginx configs + fix PM2 port override bug
Root causes found: 1. CN server (www.guanghulab.com): conflicting Nginx configs in sites-enabled and conf.d override cn-domain.conf, causing requests to proxy to a non- responsive backend → 502 2. SG server: ecosystem.config.js spreads .env.app AFTER PORT/ZY_SITE_MODE, causing .env.app's PORT=3800 to override preview's PORT=3801 → both instances fight for port 3800 → preview fails → 502 on preview domain Fixes: - deploy-cn-landing.yml: clean ALL conflicting Nginx site configs from both sites-enabled and conf.d before installing cn-domain.conf - deploy-cn-landing.yml: enhanced health check diagnostics to detect config conflicts and validate correct service identity - ecosystem.config.js: move ...appEnv BEFORE instance-specific PORT and ZY_SITE_MODE to ensure PM2 config takes priority over .env.app Agent-Logs-Url: https://github.com/qinfendebingshuo/guanghulab/sessions/80f409c9-7f98-443e-9c31-21111194a523 Co-authored-by: qinfendebingshuo <207279273+qinfendebingshuo@users.noreply.github.com>
