I have moved a website to a new Google Cloud server, using Wordpress Bitnami. http://www.medcartel.com/
The domain medcartel.com had an existing SSL certificate on the old server.
However I am having trouble to move the certificate across into the new server. I have tried FTP however it appears to have failed.
When I run a fresh Certbot certificate request (sudo certbot --apache) I get a failure due to: (# HTTP-01 challenge)
As it appears there is already a valid certificate on the old server.
What is the best way to fix this? Should I remove the SSL from the old server and re-install a fresh?
Look forward to your thoughts.
