Cant validate data

Hello, i have just installed let’s encrypt on a server i manage through plesk, altought i have SSH access i found it easier to just install it on plesk, it ran without errors but i cant access the domain i have created the certificate for. It says it cant check for the autenticity of the data provided. I dont know and cant find if I need to do anything else or i just misread the instructions to do that.
I wild gladly appreciate any help with this. Thank you all.

My domain is:

I ran this command: installed via plesk

It produced this output: says everything is fine

My web server is (include version):Apache2

The operating system my web server runs on is (include version): Ubuntu 14.04.3 LTS

My hosting provider, if applicable, is: strato

I can login to a root shell on my machine (yes or no, or I don’t know): yes

I’m using a control panel to manage my site (no, or provide the name and version of the control panel): plesk

I still cant figure this out, can someone point me on where i have to look at least?

openssl s_client -connect -servername                       
3061171596:error:140790E5:SSL routines:ssl23_write:ssl handshake failure:s23_lib.c:177:

It looks like the default SSL configuration in Ubuntu 14.04 (or Plesk when run on that operating system) might be incompatible with modern clients.

You can apply the Mozilla-reccomended Intermediate SSL configuration to your server:


This should make it happier.
