I am trying to install GoDaddy’s Managed SSL product on my domain website. To do so, GoDaddy set up requires the following: "URL (or IP address), username and password for the server that hosts your site." Apparently Fastly hosts the site, and I found the IP address 151.101.130.159 using a lookup tool. (I did not set up my website so do not know many of the internal workings. Until now I’ve never heard of Fastly.)
My question is: how do I acquire the username and password for the Fastly server that hosts my website? I”m not aware of having a Fastly account - I’m wondering if my website consultant who set the site up has the credentials. He disappeared at least a decade ago.
I appreciate any advice.
