I created a voucher in LNURLw to give away Satoshi coupons at a Bitcoin event.  
It worked well in testing, so I handed out the QR code at the event, but suddenly the voucher stopped working.  
In the ‘wallet of satoshi’, the QR code is recognized, but I get a ‘LNURL not found’ or ‘LNURL alerady being processed’ warning.  
Payment failed is recorded in payment history even in LNbits wallets  
Sending to ‘wallet of satoshi’ in LNbits Wallets also keeps failing.  
What could be the reason? Could it be because it’s a DEMO SERVER?
