Getting 451 with Surfshark vpn on firestick

I have recently switched to sky internet and my iptv has worked a few times. suddenly both iptv logins wont work with tivimate and I get a 451 error.

I have tried disabling sky sheild, have checked my surfshark subscription is paid for and have tried a few countries with no luck.

now I am with sky do I need to accept no iptv? :(
