Question: Website hosted on Plesk server is not accessible: ERR_TOO_MANY_REDIRECTS


Applicable to:

• Plesk for Linux
• Plesk for Windows

Symptoms

• Website hosted in Plesk is not working with the following error in web browser:

Code Select Expand

ERR_TOO_MANY_REDIRECTS


• Redirect checkers, like redirect-checker.org, show that the site is redirecting to the www.subdomain and back again

• Running the following curl command ends with error curl: (47) Maximum (50) redirects followed:

# curl -IL http://example.com
...
...
HTTP/2 301
server: nginx
date: Fri, 12 Sep 2025 21:12:27 GMT
content-type: text/html; charset=iso-8859-1
location: http://www.example.com.com/
strict-transport-security: max-age=15768000; includeSubDomains
x-powered-by: PleskLin

curl: (47) Maximum (50) redirects followed


Cause

There is more than one redirect configured in the site, which results in a loop, sending traffic back and forth between the naked domain (example.com) and its www. subdomain (www.example.com).

This can happen if the redirection is already configured in .htaccess, in Apache & nginx settings, or in the web application's settings (e.g. WordPress, Joomla, Drupal, etc.).


Resolution

To fix the issue, one of the redirects has to be disabled. To disable the ones from Plesk, follow these steps:

1.Log into Plesk

2.Go to Domains > example.com > Hosting & DNS > Hosting

3.Change Preferred domain to "None" and press OK
