I had the exact same issue when I tried to set it up initially. Not sure what fixed it, but after one of the latest updates I was finally able to scan and pay one of the invoices. What version of albyhub do you have installed?
nostr:npub1xv8mzscll8vvy5rsdw7dcqtd2j268a6yupr6gzqh86f2ulhy9kkqmclk3x any ideas? Sounds like an issue I also had. Couldn’t pay the invoice to open a new channel, no matter which wallet I used.
