Server Denies Access

My two android products both have comprehensive AVG protection.  My wife's iPhone uses other protection.  Each time I try to access Expedia via either MS Edge of Google Chrome I am denied access with this type of message -

Access Denied

You don't have permission to access "http://www.expedia.co.uk/?" on this server.

Reference #18.9d8f655f.1581104152.108a71eb

My wife immediately gains access!

Can anyone help please?  And give me some simple instructions as to how to get through to them.

Thanks Community!
