Colonial First State website not load on my desktop but loads on my laptop

One of the web sites I visit on a daily basis is  Colonial First State. I have a desktop and a laptop, both devices are running MACOS version 26.6.2 and Safari (version 21624.5.1.11.3 ) is my default web browser on both devices. CFS did an update on 22/8/2019 and my account does not load on my desktop but it loads on my laptop≥ I have  cleared the cache on my desktop but it makes no difference, Other websites visit reguarly behave normally, Any clues?
