import from can’t reach following url...

Hi,
I have a server installed and managed by CWP, I use PHP 8.1.20...

I have WordPress installed and a theme for which I need to run the demo... but it doesn't work, it keeps giving me a timeout..

I received the following response from the author of the theme:

"The only reason we can think of is that the server where you are running the import from can’t reach following url: https://ХХ.wp.com . It is needed because it downloads all images used in the demo from there.

This could lead the script to timeout and we are forcing it to try again up to 10 times before failing at the end.

This is the only reason we can think of. So if above suggestion doesn’t work, the only other way is to use hosting service."

Please help, what to do or which settings to change...

Thanks in advance!

You've whitelisted the required domain on the firewall? And you aren't running a WordPress security plugin that may be interfering (Wordfence, iThemes Security)?
