i tried to upload the certificate to the droplet, but it shows me an error. We sent an email before about changing the server configuration, but it destroys the server and makes the website unable, so i get it back to normal to make it work again, and it works. But now how i can upload my certificate to the website which i bought from Godaddy? And the error that appears to me what does it mean and how i can solve it (invalid certificate data tls: failed to find any PEM data in key input.) ?
