 ## Verhindern in Zukunft
 
-1. **Entrypoint-Script:** Das Entrypoint-Script behebt das Problem automatisch beim Container-Start
-2. **Image-Build:** Idealerweise sollte die `sites-available/default` Datei im Docker-Image bereits korrekt konfiguriert sein
-3. **Alternativ:** Entferne `sites-available/default` komplett und verwende nur `conf.d/default.conf`
+### Nach jedem Deployment
+
+**WICHTIG:** Nach jedem Deployment (Push zu staging-Branch) muss dieser Fix ausgef?hrt werden, da die Container neu erstellt werden.
+
+```bash
+# Mit Ansible (empfohlen)
+ansible-playbook -i deployment/ansible/inventory/production.yml \
+  deployment/ansible/playbooks/fix-staging-502-quick.yml
+
+# Oder manuell
+cd ~/deployment/stacks/staging
+docker compose exec -T staging-nginx sed -i '/upstream php-upstream {/,/}/s|server 127.0.0.1:9000;|server staging-app:9000;|g' /etc/nginx/sites-available/default
+docker compose restart staging-nginx
+```
+
+### Langfristige L?sungen
+
+1. **Entrypoint-Script:** Das Entrypoint-Script behebt das Problem automatisch beim Container-Start (implementiert, aber nicht 100% zuverl?ssig)
+2. **Deployment-Script:** Erweitere `.gitea/workflows/build-image.yml` um einen Post-Deployment-Fix (siehe TODO unten)
+3. **Image-Build:** Idealerweise sollte die `sites-available/default` Datei im Docker-Image bereits korrekt konfiguriert sein
+4. **Alternativ:** Entferne `sites-available/default` komplett und verwende nur `conf.d/default.conf`
+
+### TODO: Deployment-Script erweitern
+
+Das Deployment-Script in `.gitea/workflows/build-image.yml` sollte nach Zeile 991 erweitert werden:
+
+```bash
+# Fix nginx upstream configuration - critical fix for 502 errors
+echo "?? Fixing nginx PHP-FPM upstream configuration (post-deploy fix)..."
+sleep 5
+docker compose exec -T staging-nginx sed -i '/upstream php-upstream {/,/}/s|server 127.0.0.1:9000;|server staging-app:9000;|g' /etc/nginx/sites-available/default
+docker compose exec -T staging-nginx sed -i '/upstream php-upstream {/,/}/s|server localhost:9000;|server staging-app:9000;|g' /etc/nginx/sites-available/default
+docker compose exec -T staging-nginx nginx -t && docker compose restart staging-nginx
+```
