i don't think its a you problem. somehow his ln address is in lud06 field.
Discussion
i've had it like that for two weeks or so? i've been getting tips from Damus users.
he's right. your ln address is in lud06 (LNURL) instead of lud16 (LNADDR):

i re-entered my address and i believe it's correct now. i see a lightning bolt beside posts on astral.ninja.
Yes, now I can see the tip LN, but it doesn't work...

Well, that's the issue, my BTCPay server has the callback URL in http and I don't know how to get it to say https. I keep changing docker env variables, but I must be missing something somewhere either in the app itself or a config setting.
