Avada Wordpress wp_remote_get() - wordpress

Question

Hello All I am at a loss of what to do on our word press site it is saying
wp_remote_get() failed. Some theme features may not work. Please
contact your hosting provider and make sure that
https://build.envato.com/api/ is not blocked.
So I have contacted Avada and they said to make sure it is not blocked I have checked with our system admin twice and it is not blocked and he added to our exceptions list to make sure it can go through. I am still getting the error New to word press and Avada and not sure what I need to do next.

Answer 1

I just had this issue with Avada Theme.
Installing php-curl extension, fix the job. Basically, I think
behind the scene it uses curl to communicate with other endpoints.
But they should be given a warning like Curl is not installed, something like they are done for GD, ZipArchive etc.
