Fix: Subdomain Error Message: This site can’t be reached

In this article, we will learn how to solve a common subdomain error message. “This site can’t be reached” on a web browser.

There are sometimes after creating a subdomain you discover that an error message comes up whenever you try to navigate your web browser to the subdomain URL, the error says “This site can’t be reached.”

In recent days, so many people are complaining about it, and don’t know the way around.

Just before dropping this post, I come across it. I am going to tell you the cause, and show you how to solve it.

Once you come across this issue, the first thing you should do is to make sure that you input the right URL.

If the URL is correct, then it is certain that your site is running on Cloudflare CDN, if yes, then you will need to add the new subdomain manually from your Cloudflare dashboard. To do this, follow the step below.

Cloudflare is always the cause of this issue. If you added a domain to Cloudflare, then you have to add to subdomains as well if you don’t then you are likely to face the same issue.

How to add a subdomain to Cloudflare

1. Log in to your Cloudflare account, and select the domain which subdomain you want to add.

2. Click on DNS

3. When the DNS page opens, then you will need to add a new DNS record to the existing ones. See the image below.
