Common Causes & Solutions

1. Disk Space Full

# Check space
df -h /

# Clean Docker
docker system prune -a --volumes
# WARNING: This removes unused data!

2. Memory Issues

# Check memory
free -h

# Restart to free memory
systemctl restart docker

3. Database Corruption

# Check PostgreSQL
docker logs generated_postgres_1 --tail 100 | grep ERROR

# If corrupted, may need to restore from backup

4. Certificate Issues

# Check certificate
docker logs generated_letsencrypt-nginx-proxy-companion_1 --tail 50

# Force renewal if needed
docker exec generated_letsencrypt-nginx-proxy-companion_1 /app/force_renew

If Nothing Works

1. Check Hostinger Panel: Ensure VPS is running and not suspended
2. Check DNS: Verify domain still points to correct IP
3. Restore from Backup: Use the backup we just created

Prevention

• Set up monitoring: uptimerobot.com for free monitoring
• Regular backups: Run backup script weekly
• Check disk space: Add cron job to alert on low space
