Yes makes sense, I chose to test on VPS for better clearnet reliability & uptime, so this issue makes sense. My node is the funding source for this LNBits instance, but maybe cashu can't identify that somehow (since instance is not hosted on same hardware as pubkey)

I made a super quick sites page about the mint & contact information here: https://TinyUrl.com/thesupermint

Thank you very much for making a mint review & search nostr client. Very much needed indeed!
