Looks like you don't have access to the Org or the Org doesn't exist.
Redirecting in 2s... Do I need somehow to connect Tigris and Fly.io and tell that I am the same user who owns both accounts? For now, I am just curious to be able to list the objects in the bucket.
Thank you for any hint.
Solution
Tigris and Fly.io have separate organization management systems. Signing in through Fly.io is the only way to access your Fly.io account and organization in the Tigris Dashboard.
If you log in to the Tigris Dashboard using other methods (Google, GitHub, or username and password), you will sign in to a Tigris-native account and Tigris-native organization(s). This account is separate and not tied to your Fly.io account, and you will not be able to access your existing Fly.io organization from it.
If you want to continue using your existing Fly.io organizations, you should log in using the Fly.io sign-in method.
