Web Interface Troubleshooting - Quick Start

The Problem

After reorganizing the web interface, it doesn't seem to run and shows no logging.

Why You're Not Seeing Logs

The web service logs to syslog, NOT stdout!

The systemd service is configured with:

StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=ledmatrix-web

Immediate Actions (Run on Raspberry Pi)

1. Run the Diagnostic Script

ssh ledpi@<your-pi-ip>
cd ~/LEDMatrix
bash scripts/diagnose_web_interface.sh

This automated script will check everything and tell you what's wrong.

2. View the Actual Logs

# View recent logs
sudo journalctl -u ledmatrix-web -n 50 --no-pager

# Follow logs in real-time
sudo journalctl -u ledmatrix-web -f

3. Check Service Status

sudo systemctl status ledmatrix-web

4. Try Manual Start (Best for Debugging)

cd ~/LEDMatrix
python3 web_interface/start.py

This will show errors directly in your terminal.

Most Likely Issues

Issue 1: web_display_autostart is False

The web interface is designed NOT to start if this config is false.

Fix:

nano ~/LEDMatrix/config/config.json
# Change: "web_display_autostart": true
sudo systemctl restart ledmatrix-web

Issue 2: Service Not Started

Fix:

sudo systemctl start ledmatrix-web
sudo systemctl enable ledmatrix-web

Issue 3: Import Errors

Fix:

cd ~/LEDMatrix
pip3 install --break-system-packages -r web_interface/requirements.txt
sudo systemctl restart ledmatrix-web

Full Documentation

  • Comprehensive Guide: docs/WEB_INTERFACE_TROUBLESHOOTING.md
  • Reorganization Info: WEB_INTERFACE_REORGANIZATION.md

After Fixing

Once it's working, you should see:

  • Service status: "active (running)" in green
  • Accessible at: http://<your-pi-ip>:5000
  • Logs showing: "Starting LED Matrix Web Interface V3..."

Need Help?

Run the diagnostic script and share its output - it will show exactly what's wrong!
