Convert freepbx org

Hello guys,

I hope everything is okay

why I can not access to curl -s https://convert.freepbx.org | bash

and  

curl -s https://convert.freepbx.org | bash

we are taking this kind of error:

 [root@freepbx ~]# curl --insecure https://convert.freepbx.org | bash

curl: (7) couldn't connect to host

Could you help me to solve this issue ? because the link  https://convert.freepbx.org not available.

Thank You appreciate any help.
