Thank you dude, I had already tried with a bridge server without luck.

But I tried again today and dig a bit more and it turned out that the issue was about the macaroon thing that I did wrong before. It's all good now I have my own LNadress.

Yep I'll keep it for my friends and will display the custodial ones for tipping online.

Does it not complicate things if my LNBits instance runs on Umbrel behind Tor ? Will dig again here too lol
