Find why a local sign-in failed with zitadel logs
zitadel logs now shows the local server's warnings in yellow and its errors in red, and --level warn shows only those, so the reason a sign-in failed is easy to find. zitadel start and zitadel doctor say to keep zitadel logs --follow open, and zitadel logs works from an app inside the directory zitadel start ran in.
