How we fix Cloudflare 403 error?

This error must be fixed from the server end as the error will be usually caused by the server itself.

Here are the steps our Support Engineers follow to fix this error message.

1. First, we check if there are any IP blocks set in the account. For that, we run the below command to check for any IP block.

iptables -L INPUT -v -n

2. Next, we check the .htaccess file to see if there are any faulty rules set in the file. In case, if there are any such rules then we remove those rules and test the website if it works.

3. We try clearing the browser cache. A browser cache can also cause this error because the DNS cache might be pointing to the old server in case if there are any recent changes made in the DNS,

Or else, we simply access the website using some other browser and check if it works. If it works well without any error then it confirms the issue to be with the browser cache.

4. Also, we suggest customers enable the SSL on the domain. If there are no SSL certificates uploaded in Cloudflare for any subdomain then Cloudflare will display this error message.

So, it is necessary to have an SSL set for the domains if we are accessing the website with a secure connection.
