Sage 300 2023 PU4

Installing Sage 300 2023 with PU4 on a brand new server

I have set up the Vault and store database as per notes etc

When I open database set up and enter the vault and store info - it says

Failed to establish vault and store databases Please ensure vault owner has assigned correct roles

I have rechecked and definetly roles are correct per notes

Anyone know how to move forward
