We did some zap tests on this note… we made four attempts to⚡zap this note, at sazmining@speed.app, over a period of 13 minutes. 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://appapi.tryspeed.com/lnurl/9cce47b509a024d3d6981433a031bc350818b4f70fe0c96b0c1332af530bcb84 ). Your server did not produce an invoice, thus the zap failed. You might want to look into using a cloud-based Lightning node which is optimized for Nostr zaps, to get your zaps working.
