we tested zaps on this note… we made six attempts to⚡zap this note, at barcelona@vlt.ge, over a period of 10 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://vlt.ge/pay_callback/barcelona ). your server did not produce an invoice, thus the zap failed. the error we got was "status: Internal, message: "protocol error: received message with invalid compression flag: 52 (valid flags are 0 and 1) while receiving response with status: 404 Not Found", details: [], metadata: MetadataMap { headers: {"content-type": "text/plain; charset=utf-8", "x-content-type-options": "nosniff", "content-length": "19", "date": "Sat, 18 Oct 2025 19:50:11 GMT"} }". if you wanted to fix this... you could try getting a free rizful lightning address -- https://rizful.com ... if u get it set up, pls reply here so we can do this ⚡zap test again.
