Domain redirection problem

This is strictly a mobile phone problem. The desktop version of my wordpress site is fine.

I created a site on a subdomain, hardware.soletexfabrics.com

When I enter that exact url on my phone the site is responsive. But when I enter these two redirected domains with masking from Godaddy, the site is NOT responsive.

https://www.connectionsdraperyhardware.com
https://www.connectionsdraperyhardware.ca

The desktop version of the site works fine but it’s just the responsive version with those domains that is just not working. I’ve searched for solutions and nobody can give a straight answer. I’m thinking about asking the client to transfer the domains to the hosting company but I’m not sure if that is gonna solve the problem either. The client just insists that the registered domains be displayed instead of the subdomain url.

Any advice or lead to a solution would be much appreciated.

Thanks!
