La x lave está en los relay que tienes configurado en cada cliente

Testing zap receipts for this note… we made six attempts to⚡zap this note, at hennakamado@speed.app, over a period of 11 minutes. Six of the zaps were successfully paid... Please check for 6 satoshis received. Problem: we found that your lightning address server **did not* properly produce zap receipts, and/or didn't send the zap receipts to the relays specified in the zap. This means that nobody else could see see that you got zapped... no number appears next to the ⚡icon after zapping.... You might want to look into using a cloud-based Lightning node to get more reliable zaps.

Testing zaps for this note… we made one attempts to⚡zap this note, at tierrajusticia@lifpay.me, over a period of about 60 seconds. In each case, we found that your lightning address server did not respond correctly. (The failure point was when we did a GET request to your specified callback URL: https://lifpay.me/api/ln/lnurl/payreq/tierrajusticia_414036 ). Your server did not produce an invoice, thus the zap failed. The error we got was "Receive or send bitcoin is currently unavailable, please refer to announcement. ". You might want to look into using a cloud-based Lightning node which is optimized for Nostr zaps, to get your zaps working.
