If you are unable to regenerate a new SSL Certificate in Plesk we have wrote a guide on how you can manually export and import your existing SSL Certificate.
This does not work for LetsEncrypt as they disable the ability to export SSL certificates with Private Keys.
Note this guide requires your computer to be running Microsoft Windows.
1. Download and extract the ZIP file attached to this document
2. Open command prompt and navigate to the folder you just extracted.
Exporting the old SSL
3. In your web browser login to SolidCP at http://184.108.40.206/
4. Go to Websites and select your domain name. Click the SSL Tab and click Export Certificate, make a password that you will remember for one of the next steps.
download the domain.name.pfx file to the ssl folder you extracted from step 1.
Converting your Exported PFX to Importable PEM File
5. go back to your CMD window and run the following command
openssl.exe pkcs12 -in your-domain-name.com.pfx -out cert2.pem -nodes
you will then be asked to enter the password from Step 4. Type this and hit the enter key.
This will then generate a file called cert2.pem inside the same folder.
Check your account has SSL Enabled
6. Login to Plesk at https://plesk-6.ukdns.biz:8443
and go to your domains page
You will see SSL/TLS Certificates with 1 of 2 Icons
is a padlock:
is a document with a red award in bottom right corner:
If you see Icon 1 (padlock skip to step 7 "Install the SSL Certificate
If you see Icon 2 with the document and TLS/SSL lower down the page then do the following to enable SSL and convert to Icon 1:
Click Hosting Settings
then tick SSL/TLS Support (do not tick any other boxes at this stage).
Click OK at the bottom of the page to save this setting.
You should now see the padlock like Icon 1 above.
Install the SSL Certificate
7. Click the Padlock Icon
8. on the right hand side click upload button under under a .pem file
9. Select the .pem file we created earlier on cmd.
This will then complete the SSL installation. We also recommend enabling these 3 options to
1. auto redirect HTTP to HTTPS
2. Enable HSTS strict rules
3. Auto renew SSL when it expires
If you have other SSLs to migrate please remember to delete the existing .pfx and cert2.pem file from your SSL folder on your PC.
