Cody Tseng there is some bug on jumble.social that prevents it from requesting notes from wss://lockbox.fiatjaf.com/ in some cases:

See how it tries once, gets an "auth-required:" and authenticates, but then it doesn't try again. Simultaneously the same thing happens with the kind:0 query, but that one is tried again. Since I put both wss://lockbox.fiatjaf.com and wss://zapbox.fiatjaf.com in the same relay set they're both queried at the same time and for wss://zapbox.fiatjaf.com all seems to work fine, so maybe this is a race condition? I don't know:

There are no errors in the console.
