Cannot extend or upgrade my Avast subscription

Avast Free Antivirus / Premium Security
1

My Avast free licence expires in 5 days time and am thinking of upgrading to Premium Security.

When I click on the link to do either of these I get the message

HTTP header is larger than 8192 bytes.

How do I get round this.
