Few things are as frustrating as opening a website and being greeted with a browser error instead of content. One of the most confusing messages users and site owners encounter is ERR_TOO_MANY_REDIRECTS. It sounds technical, and in many ways it is—but the root cause is often simpler than you’d expect.
At its core, this error is the result of redirect rules fighting with each other. A page keeps sending the browser in circles until it finally gives up. Understanding why this happens is the first step toward preventing it—and that’s exactly what this article is here to help with.
If you’re looking for a deeper, step-by-step troubleshooting guide after reading this, our main blog on redirect errors breaks it down in more technical detail and is a great follow-up read.
What Does ERR_TOO_MANY_REDIRECTS Actually Mean?
A redirect is supposed to be helpful. It tells the browser, “This page has moved—go here instead.” Problems arise when redirects form a loop.
Here’s a simple example:
- Page A redirects to Page B
- Page B redirects back to Page A
The browser keeps bouncing between them until it hits a limit, then throws the ERR_TOO_MANY_REDIRECTS error.
This can happen at the browser level, server level, CMS level, or all three at once. The tricky part is that even one small misconfiguration can trigger the issue.
Common Redirect Misconfigurations That Cause Problems
Conflicting HTTP and HTTPS Rules
One of the most common causes is conflicting rules for HTTP and HTTPS.
For example:
- Your server forces HTTP → HTTPS
- Your CMS or CDN forces HTTPS → HTTP
The browser gets stuck switching protocols endlessly. This happens frequently after installing SSL certificates or migrating a site to HTTPS without checking existing redirect rules.
Our main blog goes deeper into SSL-related redirect conflicts and shows how to identify where the loop starts.
WWW vs Non-WWW Redirect Loops
Another classic mistake involves the “www” version of a site.
- Server rule redirects example.com → www.example.com
- CMS setting redirects www.example.com → example.com
The result? A never-ending loop.
This often happens when DNS, hosting settings, and CMS preferences aren’t aligned. Everything looks correct individually, but together they create a redirect war.
CMS and Plugin Conflicts
Content management systems like WordPress make redirects easy—but also risky.
SEO plugins, security plugins, and caching plugins may all add redirect rules. When multiple plugins try to control the same URLs, conflicts are almost guaranteed.
You might not notice the issue immediately. Sometimes the error appears only after a plugin update or a settings change, which makes diagnosis even more confusing.
How Browsers and Search Engines React to Redirect Loops
The majority of browsers are relatively tolerant; however, they also have limits. After a certain point has been reached, a browser will stop that request and would display ERR_TOO_MANY_REDIRECTS.
Search engine spiders, on the contrary, are usually not as forgiving.
If Google encounters a redirect loop while trying to crawl your site, the following could occur:
- Indexing could stop
- Ranking could decrease
- Crawl budget could be wasted
For these reasons, it’s not only important from a user experience perspective to correct misconfigured redirect settings, it is an extremely important factor for your SEO.

Real-World Example: A Small Change, Big Problem
For example: A site owner switches hosting providers, the new hosting provider automatically creates server-level HTTPS redirect rules for the site, when the site already had HTTPS forced via a plugin.
Individually, both rules are correct. Together, they create a loop.
The site goes down, visitors see errors, and traffic dips overnight. This is a surprisingly common scenario—and a good reminder that redirect rules should always be reviewed after any infrastructure change.
How to Prevent Redirect Misconfigurations
Audit Redirects Regularly
Don’t wait for errors to appear. Periodically review:
- Server-level redirects (.htaccess or Nginx config)
- CMS settings
- Plugin-based redirects
- CDN redirect rules
Having one clear “source of truth” for redirects prevents conflicts.
Make One Change at a Time
When fixing redirect issues, change only one thing, then test. Multiple changes at once make it impossible to know what actually solved—or caused—the problem.
Testing in an incognito browser or using online redirect-checking tools can help you spot loops quickly.
Keep Redirect Logic Simple
The more complex your redirect setup, the higher the risk. In most cases, you only need:
- One HTTPS rule
- One canonical domain rule (www or non-www)
- Minimal page-level redirects
Anything beyond that should have a clear reason.
Why Understanding the Cause Matters More Than the Fix
It’s tempting to look for a quick fix when you see ERR_TOO_MANY_REDIRECTS, but blindly disabling plugins or deleting rules can create new problems.
Understanding why the loop exists helps you fix it cleanly—and avoid repeating the mistake later. It also makes future site migrations, SSL renewals, and redesigns far less stressful.
Our main blog does an excellent job of walking through structured troubleshooting steps once you’ve identified the likely cause.
Final Thoughts: Don’t Let Redirects Undermine Your Site
Redirects are powerful tools when used correctly—and dangerous when misconfigured. A single conflict can break your site, frustrate users, and hurt your SEO without warning.
