AX7 Environment startup issues

The Test environment I am working on is giving me a "HTTP Error 503. The service is unavailable.". This is on an application release 7.3 and platform update 12

When I look at the event logs I am seeing these errors and warnings:

Failed to create a metadata service client in 5 attempts.

Received the following exception when contacting the AX Metadata Service possibly due to expired token. Attempted to retry the operation 5 times with no success. The HTTP service located at localhost/.../MetadataService is unavailable. This could be because the service is too busy or because no endpoint was found listening at the specified address. Please ensure that the address is correct and try accessing the service again later.

Metadata service communication retry attempts failed to resolve issues with the following settings AX7CertificateUserName: FRServiceUser@dynamics.com; AX7CertificateThumbprint: CB3BDAE89EFA5B268A3ED88D2C5A96EBF9C791B5; AX7FederationRealm: spn:00000015-0000-0000-c000-000000000000; AX7ProviderName: mintedtoken.dynamics.com; AX7TokenIssuer: fakeacs.accesscontrol.windows.net

The description for Event ID 110 from source Microsoft Dynamics 365 for Finance and Operations, Enterprise edition cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

If the event originated on another computer, the display information had to be saved with the event.

The following information was included with the event:

Has anyone seen this before? Any help would be much appreciated.
