First of all - for PTA you need PTA agent installed, probably it was installed. Second - are you sure, that after fresh installation of AAD Connect you set the same settings? Did synchronization of accounts between on-premises and Azure AD working fine? It should be visible information about synchronization errors in Office 365 admin portal home page or Azure Active AD - Connect Health blade. Of course you need use cloud account to logon if PTA is not working properly.
