We tested zaps on this note… we made seven attempts to⚡zap this note, using your lightning address starting with "thatdudeluke", over a period of 15 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://getalby.com/lnurlp/thatdudeluke/callback.) Your server did not produce an invoice, thus the zap failed. We recommend that you use a cloud-based Lightning node which is optimized for Nostr zaps, to get your zaps working.
