+# 🔧 Deployment Issue Fixes
+
+## 🔍 Issues Identified from Latest Log
+
+### **Issue 1: TypeScript JSX Configuration Missing** ❌→✅
+**Problem**: TypeScript compilation failing with `error TS6142: '--jsx' is not set`
+**Root Cause**: Generated tsconfig.json in Docker was missing JSX configuration
+**Fix Applied**: Added `"jsx":"react-jsx"` to the tsconfig.json generation in Dockerfile
+**Line Fixed**: Line 77 in Dockerfile
+
+### **Issue 2: Health Check Tool Mismatch** ❌→✅
+**Problem**: Health checks failing with `wget: can't connect to remote host: Connection refused`
+**Root Cause**: 
+- Dockerfile uses `curl` for health checks
+- Coolify deployment system uses `wget` for health checks
+- Tool mismatch causing health check failures
+
+**Fix Applied**: 
+1. Added `wget` installation alongside `curl`
+2. Updated health check command to support both tools: `curl -f http://localhost/ || wget -q --spider http://localhost/ || exit 1`
+
+### **Issue 3: Container Health Check Endpoint** ❌→✅
+**Problem**: Health check trying to access `/health` endpoint that doesn't exist
+**Fix Applied**: Changed health check to use root path `/` which always exists for Nginx
+
+## 📋 Changes Made
+
+### **1. Updated Dockerfile (Lines 77, 89, 113)**
+```dockerfile
+# Fixed TypeScript JSX configuration
+RUN echo '{"compilerOptions":{..."jsx":"react-jsx"...}}' > tsconfig.json
+
+# Added wget for Coolify compatibility
+RUN apk add --no-cache curl wget
+
+# Fixed health check with fallback
+CMD curl -f http://localhost/ || wget -q --spider http://localhost/ || exit 1
+```
+
+## ✅ Expected Results
+
+After these fixes:
+
+1. **TypeScript Build**: ✅ Should compile `.tsx` files successfully
+2. **Health Check**: ✅ Should pass using either curl or wget
+3. **Container Status**: ✅ Should show as healthy
+4. **Deployment**: ✅ Should complete without rollback
+
+## 🎯 Root Cause Analysis
+
+The deployment failures were caused by:
+1. **Build Configuration**: Missing JSX support in generated TypeScript config
+2. **Health Check Compatibility**: Tool mismatch between Docker image and deployment platform
+3. **Endpoint Mismatch**: Health check looking for non-existent endpoint
+
+## 🚀 Next Deployment
+
+The next deployment should:
+- ✅ Build successfully with JSX support
+- ✅ Pass health checks with both curl and wget
+- ✅ Complete without rollbacks
+- ✅ Result in a fully functional application
+
+**Status**: Ready for redeployment with fixes applied! 🎉
