HCW8064 error

I continue to get the HCW8064 when running the the Exchange Hybrid configuration. I have tried manually creating the OAuth by using the steps here https://learn.microsoft.com/en-us/exchange/configure-oauth-authentication-between-exchange-and-exchange-online-organizations-exchange-2013-help?redirectedfrom=MSDN

On step 1 I continue to get Cannot acquire auth metadata document from 'https://accounts.accesscontrol.windows.net/<domain>/metadata/json/1'
33978-error2.jpg

I can go to that location through a browser just fine. I have search the internet everywhere and cannot find a solution to this issue. I am hoping someone has had this issue also and can provide some steps to get passed it. I have verified that it has the correct permissions as well.

We are running Exchange 2013 CU23

Thanks in advance.

    @Chris Klein

    Did you try to rerun the Hybrid Configuration wizard?
    In general, re-launching Hybrid Configuration Wizard does the trick. Before re-running HCW, please re-download Office 365 Hybrid Configuration Wizard to make sure you are using the latest version.

    If you still get HCW8064 error, please post the screenshot of the error page, and don't forget to cover your personal information.

    Before manually configuring OAuth authentication, there are two points must be paid attention to:

    1. Make sure you are using the administrator account which is a member of Organization Management role group.
    2. Double-check and confirm that the domain used in AuthMetadataUrl is verified successfully and it's used as the primary SMTP domain for the cloud-based email accounts.
