Failing to use designcloud

I am on an nginx, ubuntu 20, php 8, wordpress combo with root access and vps.
I never had any issue with imports from designcloud.
Suddenly for last 2-3 days I am unable to import anything from designcloud.
The error that shows up on Chrome developer is
Access to XMLHttpRequest at 'https://demo.theme.co/designcloud/wp-json/design-cloud/v3/asset/483?credentials= (removed the credentials) from origin ‘https://example.in’ has been blocked by CORS policy: No ‘Access-Control-Allow-Origin’ header is present on the requested resource

And
GET …net: ERR_FAILED_200
This is happening only when I am trying to import full sites, any full site, and not when I am trying to import a header or footer or any other such element.
There are no pages or posts on the new site.

Any help would be appreciated. This is happening right when I am building a new site,

Hi @Powercloner ,

I can confirm there was an issue on our end (since yesterday afternoon) where requests to Design Cloud site installs have been failing. This has been corrected. Please give it a try again and let us know how it goes. Thank you!

@alexander,
Thank you for the prompt response.
The issue is resolved now.
Thanks again.
