to be honest, that’s the first time i see this error. however i’m not much of an expert anyway.
interested in seeing a solution, update if you find one. thanks
No you can’t use an app access token with the Kraken Channels endpoint as when you don’t declare a channel ID it returns the channel for that token, And a App Access Token has no channel.
This suggests your token has expired. hence the 401
The generate advice is to migrate to Helix if you can rather than using V5.
