Eon website blocked as blacklist

Hi I am unable to access

https://www.eonenergy.com/for-your-business/small-to-medium-energy-users/your-account

as it comes up with blocked url:blacklist. This is the account I use for my energy provider and have had no previous issues.

Can anyone help please ?
Thanks
