fyi, mistery solved: alby recently moved nostr keys from general settings towards account specific. I had my nostr nsec in my alby account but I hadn't add it to LightningTipBot account, which is now my default one on nostr. Since I was already logged in iris.to, it wasn't asking again nsec for that one, but was not finding nsec upon a new login intent on snort. I just added it and it works 🖖
