Some if not most VPNs are blocked by tradfi. You can try changing your VPN to another US region. Chances are you’ll have to temporarily disable VPN. Or you can change your bank 😃.

I run into this a lot. For some reason, Utah is totally okay with most sites. When I change Mullvad or Proton VPN to Utah everything works fine. It's very rare that it doesn't go through after that.
Hmm, thanks i'll try.
