If your website visitors are seeing a 502 Bad Gateway or a 503 Service Unavailable error, it means your web server is struggling to communicate or is completely overwhelmed.
What Causes Server Overload?
- Traffic Spikes: A sudden influx of legitimate visitors.
- Malicious Bot Scraping: Thousands of bots scraping your content simultaneously.
- DDoS Attacks: Hackers intentionally flooding your server with fake traffic to bring it down.
How to Troubleshoot and Fix It
1. Check Your Hosting Resources
If you are on a cheap shared hosting plan, you might just need to upgrade your server resources (CPU/RAM). Contact your host to see if you are hitting your limits.

2. Block Malicious Traffic with a Firewall
If the traffic spike is artificial (bots or DDoS), upgrading your hosting is a waste of money. The attackers will just send more bots until your new server crashes too.
The only permanent solution is an intelligent Web Application Firewall. Nexura Security analyzes incoming traffic in real-time. It seamlessly allows human visitors through while instantly blocking DDoS attacks, bad bots, and scrapers.
