We've recently purchased ADselfservice plus portal, we've gone through of configuring everything so where able to access the portal outside the network however I want to make it more secure, but we are having some issues with installing the SSL Certificate. 

We already have an wildcard SSL certificate and when I go to download the certificate from 123 Reg, it isn't an download file but text. 

Do we copy this text into notepad to then convert it to a pfx format file?

I have done the above and followed adselfservice instructions and soon as we apply the SSL and config the server.xml file we are unable to access the portal via http or https. 

Is there anything we are missing?

What is the correct process of installing the SSL certificate? We have followed pretty much followed all instructions and still not working. We've contacted ADSelfservice support and wasn't very helpful.

It would much appreciated if someone could help us.

Regards

Kevin.
