We did some zap tests on this note… we made six attempts to⚡zap this note, at smitty@zapstr.net, over a period of 1 minute. 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://zapstr.net/lnurlp/smitty/callback ). Your server did not produce an invoice, thus the zap failed. If you wanted to fix this... you could try a free Rizful account -- https://rizful.com ... when u have it set up, pls reply here so we can do this ⚡zap test again.
