Fix HTTP 500 on login and create comprehensive deployment documentation

CRITICAL FIXES: - Fixed JWT key configuration issue causing HTTP 500 on login - Changed environment variable from JWT_SECRET_KEY to Jwt__Key (double underscore) - Increased JWT key length to >32 bytes (256 bits) as required by HMAC-SHA256 - Fixed ASPNETCORE_URLS configuration (not ASPNETCORE_HTTP_PORTS) DOCUMENTATION CREATED: - TROUBLESHOOTING.md: Complete troubleshooting guide with common issues and solutions - deploy-littleshop.sh: Automated deployment script with working configuration - docker-compose.hostinger.yml: Docker Compose file with all correct environment variables - Updated WORKING_BASELINE_2024-09-24.md: Added HTTP 500 fix details ROOT CAUSES IDENTIFIED: 1. JWT key environment variable naming mismatch (Jwt__Key vs JWT_SECRET_KEY) 2. JWT key too short (was 17 bytes, needs >32 bytes) 3. ASP.NET Core URL configuration issue (ASPNETCORE_URLS vs HTTP_PORTS) 4. Database file permissions (must be owned by UID 1654) WORKING CONFIGURATION: - Jwt__Key with 79-byte key - ASPNETCORE_URLS=http://+:8080 - Proper Docker network configuration (littleshop-network) - SilverPay integration on port 8000 (not 8001) This commit ensures we have a stable, documented baseline for future updates and addresses the concern about "one step forward, two steps back" by providing comprehensive documentation of all fixes. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

+# LittleShop Troubleshooting Guide
+
+## Common Issues and Solutions
+
+### 🔴 HTTP 500 Error on Login
+
+#### Symptoms
+- Login page loads (HTTP 200)
+- Submitting credentials returns HTTP 500
+- Error: "Request reached the end of the middleware pipeline"
+
+#### Root Causes & Fixes
+
+##### 1. **JWT Key Configuration Issue**
+**Problem**: JWT key environment variable name mismatch or key too short
+
+**Error Message**:
+```
+IDX10720: Unable to create KeyedHashAlgorithm for algorithm 'http://www.w3.org/2001/04/xmldsig-more#hmac-sha256',
+the key size must be greater than: '256' bits, key has '136' bits.
+```
+
+**Solution**:
+```bash
+# CORRECT - Use Jwt__Key (double underscore)
+-e Jwt__Key="ThisIsAVeryLongSecretKeyThatIsDefinitelyLongerThan32BytesForSure123456789ABCDEF"
+
+# WRONG - These won't work
+-e JWT_SECRET_KEY="..."  # Wrong variable name
+-e Jwt_Key="..."          # Single underscore
+-e Jwt__Key="shortkey"    # Key too short (< 32 bytes)
+```
+
+##### 2. **Parameter Case Sensitivity**
+**Problem**: Form sends lowercase but method expected uppercase
+
+**Solution**: Already fixed in code - Login method now accepts both cases:
+```csharp
+public async Task<IActionResult> Login(string Username, string Password)
+{
+    var username = Username?.ToLowerInvariant();
+    var password = Password;
+    // ...
+}
+```
+
+##### 3. **Port Configuration Issue**
+**Problem**: App listening on wrong port
+
+**Solution**:
+```bash
+# CORRECT
+-e ASPNETCORE_URLS="http://+:8080"
+
+# WRONG
+-e ASPNETCORE_HTTP_PORTS=8080  # This doesn't work
+```
+
+---
+
+### 🔴 Container Shows "Unhealthy"
+
+#### Symptoms
+- Container running but marked as unhealthy
+- Health check failing
+
+#### Solution
+1. The health check includes database check which can timeout during initialization
+2. App still works even if marked unhealthy
+3. To disable health check issues, run without health check or increase timeout
+
+---
+
+### 🔴 Database Permission Errors
+
+#### Symptoms
+- SQLite Error 8: attempt to write a readonly database
+- Cannot create or update database
+
+#### Solution
+```bash
+# Database MUST be owned by UID 1654
+sudo chown -R 1654:1654 /opt/littleshop/data/
+```
+
+---
+
+### 🔴 Network Connectivity Issues
+
+#### Symptoms
+- Containers can't communicate
+- SilverPay API unreachable
+- "Name or service not known" errors
+
+#### Solution
+```bash
+# All containers must be on littleshop-network
+docker network connect littleshop-network littleshop-admin
+docker network connect littleshop-network silverpay-api
+docker network connect littleshop-network nginx-proxy-manager
+```
+
+---
+
+### 🔴 Anti-forgery Token Validation Errors
+
+#### Symptoms
+- 400 Bad Request on form submissions
+- CSRF token validation failures
+
+#### Current Status
+- Anti-forgery validation is temporarily disabled on login
+- This is noted in the code: `// [ValidateAntiForgeryToken] // Temporarily disabled for HTTPS proxy issue`
+
+---
+
+## Quick Diagnostics
+
+### Check Container Status
+```bash
+docker ps --format "table {{.Names}}\t{{.Status}}" | grep littleshop
+```
+
+### Check Logs for Errors
+```bash
+docker logs littleshop-admin --tail 50 | grep -E "Exception|ERROR|fail"
+```
+
+### Test Login Locally
+```bash
+docker exec littleshop-admin curl -X POST http://localhost:8080/Admin/Account/Login \
+  -d "Username=admin&Password=admin" \
+  -o /dev/null -w "Status: %{http_code}\n"
+```
+
+### Check Environment Variables
+```bash
+docker exec littleshop-admin printenv | grep -E "Jwt|ASPNETCORE"
+```
+
+---
+
+## Recovery Procedures
+
+### Complete Reset
+```bash
+# Stop everything
+docker stop littleshop-admin
+docker rm littleshop-admin
+
+# Clean up
+sudo rm -rf /opt/littleshop/data/*
+
+# Fix permissions
+sudo mkdir -p /opt/littleshop/{data,logs,uploads}
+sudo chown -R 1654:1654 /opt/littleshop/data/
+
+# Redeploy
+./deploy-littleshop.sh
+```
+
+### Emergency Development Mode
+To see detailed errors:
+```bash
+docker run -d \
+  --name littleshop-admin \
+  --network littleshop-network \
+  -p 127.0.0.1:5100:8080 \
+  -v /opt/littleshop/data:/app/data \
+  -e ASPNETCORE_ENVIRONMENT=Development \
+  -e ASPNETCORE_URLS="http://+:8080" \
+  -e ConnectionStrings__DefaultConnection="Data Source=/app/data/littleshop-production.db" \
+  -e Jwt__Key="ThisIsAVeryLongSecretKeyThatIsDefinitelyLongerThan32BytesForSure123456789ABCDEF" \
+  littleshop:latest
+```
+
+---
+
+## Critical Configuration Points
+
+### Must-Have Environment Variables
+```
+ASPNETCORE_ENVIRONMENT=Production
+ASPNETCORE_URLS=http://+:8080  # NOT HTTP_PORTS!
+Jwt__Key=[minimum 32 bytes]    # Double underscore!
+ConnectionStrings__DefaultConnection=Data Source=/app/data/littleshop-production.db
+```
+
+### Required Docker Network
+```
+littleshop-network (external)
+```
+
+### Required Permissions
+```
+/opt/littleshop/data: UID 1654
+/opt/littleshop/logs: UID 1654
+/opt/littleshop/uploads: UID 1654
+```
