I also get an error. There is nothing apparently wrong with the address. My guess is @Wallet of Satoshi is experiencing an outage somewhere. In fact if you send a zap to: velvetycamp15@livingroomofsatoshi.com it goes through just fine, so it’s most likely a DNS issue. https://livingroomofsatoshi.com/.well-known/lnurlp/velvetycamp15
