To verify domain ownership using HTTP verification, you will need to create appropriate files with specific text strings under your “webroot/.well-known/acme-challenge/” directory, where “webroot” is the main directory with your website pages. Please make sure that the files you have created are actually accessible (by clicking the links below in the File column) and have proper content before clicking “Next”

10. Its worth noting  that you simply need to go your www folder or htdocs or their significant other folder (the folder with the index.html file) in your control panel. Create a folder and name it webroot then open it and create another folder inside webroot  and name it .well-known (don’t forget the “.” is part of the name). Then inside the  .well-known folder create another folder and name it acme-challenge. Now upload the files you downloaded to the acme-challenge folder. Please note the this files are hash named with names like nx4RK70Sta4Om3qkAoGip94N10jpskDi_r5zAhkFfGM.txt   and not the certificate and key files.

To verify you own the domain click the link below the text files. It looks something like this

in .well-known folder add the text files

with the name of the file next to Text: YoKB39XEJGJQkUPxz-QWVK7QUEq6o3dWq-Ro6itrIYg.Bv6eQfYkVqZ_D0UwrppVCEUfSHDCSHq5y7L0VlKNGrI.

12. Go to your control panel and click on submit button to add the SSl certificate and key you copied or uploaded .

Congratulations! you added an SSL certificate to your website successfully.


The certificate expires after 6 months and therefore before its expiry you can get yourself another free certificate from zerossl. For an SSL certificate which doesn’t expire in six months buy one here at affordable price.

In most cases, you do not need to supply the CA bundle because the server will fetch it from a public repository during installation.

If you are interested in a paid SSL CERTIFICATE at affordable price then you can get yourself a paid certificate which doesn’t expire after six months and is widely accepted by different hosts here.
