Yes. Requests can fail before they reach your server.
Your server error log only records errors the server itself handles, so it stays empty. A blank log does not mean visitors saw no error. It means you must look earlier in the path.

Where requests stop before your server
Many stops sit between the visitor and your origin server. Domain name service, which turns a domain name into a server address, can fail. Content delivery networks, firewalls, and load balancers can also block or drop a request before it reaches the origin.
The origin is your main hosting server. Browser problems also leave no server trace. A broken script, blocked resource, mixed content warning, or failed form call can stop a page from working. The visitor sees a broken checkout, blank block, or endless loader while server logs stay quiet.
How do you tell early failure from server failure?
Start with what the visitor sees and what the browser records. Open browser developer tools and watch the Network tab during a fresh test. Server hits show a status code such as 404 or 500.
Early failures leave clear marks. Look for these signs: Compare the server access log with the error log. The access log lists every request the server received. If the failed visit is missing there too, the request never arrived.
- status shows failed, blocked, or network error with no server code
- page loads but the key action never sends a request
- error appears only on one network, device, or blocker setting
What should WordPress and Drupal owners check first?
Check layers that sit in front of the server. Caching tools, security plugins, and web application firewalls can block form posts, logins, and checkout calls. A wrong rule can reject visitors with a forbidden page the server never logs as an error.
Then check the theme and custom code. A JavaScript error can stop a slider, menu, payment button, or map from loading data. Test with plugins paused, a default theme active, and browser cache cleared, then repeat the exact visitor action.
How do you get proof of the missing requests?
Use records outside the server. Check firewall logs, delivery network logs, uptime checks, payment logs, and form entries. Ask one affected visitor for browser, device, address, time, and screenshot, then match that detail against those records.
Add client-side evidence for the next failure. Keep browser console output, save a failed Network trace, and record a short video of the steps. Re-test from a clean browser and a different network to show whether the break follows the site or the visitor setup.
