I ran into this yesterday when setting up. Here is what worked for me:

1. Set your VPN outside of USA

2. Download Wallet of Satoshi direct from website

3. Setup through NOSTR client to connect to WOS (I just sent 5000 SATs from Strike to fund it

4. Turn off or move VPN back to US

5. Start Zapping

This was not suppose to work but has been fine for sending and receiving
