pfSense Load Balancing with Banks

Hi All, So ive currently got dual wan using pfsense in which im always getting the Following when trying to access online banking (Santander)

This site can’t provide a secure connection sent an invalid response.


Ive searched google and found multiple attempts to fix it but would then limit the speed on other stuff as its limiting all SSL connections to 1 of the WANs.
The Load Balance is set to both Tier 1 and other than the banking sites everything works fine. Can anyone maybe recommend a set up?

Ive considered looking into maybe setting a firewall rule to force all banking connections through a Tier 1 / Tier 2 Load Balancing but its getting the list of either IPs or domain names / hosts for that to be functional
