Debugging Timeout Issues in your Web Applications

/ 1 min read

Timeouts can be a real headache, especially when you’re not sure where the problem lies. But don’t worry, you’re not alone. Let’s dive into how to debug this issue.

Let’s 🚀

Identifying the Culprit

Understand the Error Message

The first clue is always in the error message.
Google it to get more insights.

Time the Timeout

Use a stopwatch to pinpoint when the timeout occurs.
This will help you identify which component is responsible.

Making the Fixes

I’ve listed some common timeout configs. See if they match the error message or the duration that you clocked earlier.

PHP Configuration

Look for max_execution_time

Nginx Configuration

Look for proxy_read_timeout, proxy_connect_timeout

Apache Configuration

Look for Timeout, ProxyTimeout

GCP Load Balancer

Check Load Balancer settings for keepalive

Trust, but Verify

After updating, reload configs (if needed) then test to make sure the timeout issue is resolved. Hopefully, you won’t have to deal with those pesky timeout issues again.

But if you do, you know where to look.
