The error you are seeing for both issues in the thread is likely one of two things:
1. An issue with their CDN (Content delivery network) blocking your IP Address or country.
2. A security device / firewall is blocking you. This happens when your IP is listed is being or has been used by hackers, or you are located in a blocked or banned country etc.
It also possible you were visiting the site and they were having some issue with the connectivity between their servers and their CDN provider, this is less likely if it happens all the time.
Requesting help from the sites customer support team can help, they will probably forward the request to the website team to help find out.
