Demo import not working

I have been trying to import the Enfold 2017 Demo
I keep getting this error
“Importing didnt work!
You might want to try reloading the page and then try again.
I have refreshed the page and changed browsers and am still getting the same error

They said this :
We have straced the import process and noticed that your website is trying to connect to a remote server to download content, however, that remote server is not responding. Please check the following logs:

Code:
connect(5, {sa_family=AF_INET, sin_port=htons(443), sin_addr=inet_addr(“159.203.69.44”)}, 16) = -1 EINPROGRESS (Operation now in progress)

[9:10]
connect(5, {sa_family=AF_INET, sin_port=htons(80), sin_addr=inet_addr(“85.13.149.161”)}, 16) = -1 EINPROGRESS (Operation now in progress)

You can check the complete strace output here:

We can confirm all the server limits are set to the maximum allowed, but it seems the import is failing because of fact your application is unable to connect to the remote servers listed in the strace logs above.

With that being said, it will be better to contact the theme developers and provide them with the strace results, so they could investigate and troubleshoot what is causing the import process to fail.
