The Technical Contact Information is the details of the individual responsible for the installation and management of the Certificate.
If you have ordered a business SSL, you will also be required to enter your business details. These should be the correct address and phone number and legal entity name. They will be required to be validated by the Certificate Authority, any mistakes will cause delays. More information on Business Validation can be found here.

4: Click Continue to go to the next Step. Here you need to select the Authentication Method to validate your domain name. This is required to prove you own the domain name and have permission to issue an SSL Certificate for the domain.

Select the method that will be the easiest for you to use; File-Based Authentication ( HTTP / HTTPS ), CNAME Based Authentication ( DNS ) or Certificate Approver Email.

Click Continue/Submit to finish the Configuration process.

After you complete the domain validation via your selected method, your SSL will be issued. If you ordered a Business SSL, you will need to wait for the Certificate Authority to complete the Business address and phone validation. If the validation has not progressed, or you have not received your Certificate after some time, please contact our support team so we can check on its status.

Step 4. Check the SSL is working

It is a good idea to go to your website and see if it works via
We also recommend you use this tool to check the install has been completed successfully:

You may need to get your web developer, or update your website yourself, to make sure all files use https:// and all links to your site and within your website use https://

If you run a server test to check your SSL and find that you receive a rating less than an A, you may have all versions of TLS turned on. You’ll need to turn TLS 1.0 and 1.1 off and leave TLS 1.2 on.

You can do this by accessing your server via SSH and pasting in a few commands. You can find the commands here.

/usr/local/psa/bin/server_pref -s | grep ssl-protocols
#ssl-protocols: TLSv1 TLSv1.1 TLSv1.2

/usr/local/psa/bin/server_pref -u -ssl-protocols "TLSv1.2"

/usr/local/psa/bin/server_pref -s | grep ssl-protocols
#ssl-protocols: TLSv1.2

If you require any assistance with your SSL Installation please contact our friendly support team.
