Started seeing this this morning. Have torn down and rebuilt a few times with the same results.
Note that I’m using
fly postgres create and everything is within the same organization (and region, for that matter).
Error Failed attaching oab-db to the Postgres cluster oab: Get "http://oab-db.internal:5500/commands/databases/oab": connect tcp [fdaa:0:466f:a7b:2dbb:2:727c:2]:5500: operation timed out.\nTry attaching manually with 'fly postgres attach --app oab oab-db'
