GTmetrix Analysis Errors
Network Connectivity Errors
If you get errors like the following:
- “Read timeout”
- “Broken pipe”
- “Connection reset by peer”
There may be connectivity issues between our server and the GTmetrix test server.
Server Status Errors
GTmetrix only analyzes pages that return a success HTTP status code. It means, if you are receiving this error, your page has an error HTTP status code. The most common reasons for this include:
- Your web application generating the page is incorrectly returning an error HTTP status code but is returning page content that does not indicate an error.
- Your web application is blocking GTmetrix from accessing the page. With WordPress, it could be due to plugins like Bad Behavior or Wordfence. With e-commerce software, it’s common that the access is blocked based on the IP.
- You are using a reverse proxy like CloudFlare and it is blocking GTmetrix from accessing the page.
SSL Certificate Errors
GTmetrix only analyzes HTTPS sites that have a valid, trusted SSL certificate. This type of errors commonly occurs when the intermediate/chain certificates aren’t installed correctly.
If GTmetrix has problems resolving your site’s domain, then you may have DNS configuration issues or DNS records have been cached if your site has recently changed name servers.

The maximum time GTmetrix will wait for a page to load is 2 minutes. The most common reasons for this error are:
- An extremely slow loading page or resources
The URL did not Appear to be an HTML Page
To ensure that your page is an HTML page, GTmetrix checks the Content-Type header for text/HTML, because GTmetrix only analyzes HTML pages.
You also may get this error if the Content-Type header is missing or the value is empty. This problem usually occurs because of the web application, not the server.
404s are one of the most important errors you have to fix for better performance. 404 errors cause false requests and make some serious issues on your site speed. Either you have to make them go away completely by turning them into 410 from your search console or redirect to a valid URL.

Leverage Browser Caching
In this case, GTmetrix shows you the cases which are better to save in the user’s explorer cache, to increase the website loading speed.
For example, GTmetrix said that “http://…/font/calibri.woff” should save in the user’s cache.
You see by the extension and address that it is a font used for designing the website. It’s enough to say that the font with .woff extension should save in the user’s explorer cache. For this purpose, just copy the following code and paste in the .htaccess file:
<IfModule mod_expires.c> ExpiresActive On ExpiresByType font/woff "access plus 1 year" ExpiresDefault "access 1 month" </IfModule>
We made an example of what you have to do for fixing leverage browser caching error, but that’s not all. There are many different elements that are better to be cached on the browser. You can find codes for your required data in the following:

<html xmlns="http://www.w3.org/1999/xhtml"> <head> <title></title> </head> <body> </body> </html>
or use this Compressed mode:
To fix this, you’d better transfer the body section scripts to head section of the website or at the end of the body section. After all put that on a file and reference that link.
It refers to keeping alive the file between server and explorer. Just put this following code in your website’s htaccess folder:
<ifModule mod_headers.c> Header set Connection keep-alive </ifModule>
Avoid Bad Requests
It means that the requested address is no longer exist. To fix this error, you should find addresses which GTMetrix shows you in your template and delete them because it says this address is not available.
Number of Requests
GTmetrix says you have to have under 87 requests on a website. It’s an average number and the fewer requests you have, the better performance you got.
You can use WP-Rocket or Lazy Load plugin to fix this issue. For example, Lazy Load omits the value attributes of the images tag and let the site load completely, then it will put image values attributes in their previous order again. By doing this, requests during loading will be reduced and your “Time to first-byte” factor will be improved.
These are plugins that you can purchase in the Deep theme with 20% discount and their guide has been completely explained in the Deep theme documentation.
Specify Image Dimensions
This means to specify values for the width and height of the images on our website. It is better not only specify values for our images through CSS but also in HTML like the following:
<img src="#link#" alt="#description#" width="Y" height="X" />
After doing this solution, your images SEO will boost and optimize, therefore you can see that your images indexing speed will lift up.
