RE: Can't login to Dynamics 365 for operations instance Web Page Login Issue

Dear All,

Server : Windows Server 2012 R2

Hyper V : Configure VM for D365 with external switch. Internet is working fine.

D365 : 1 month trail period (Create new account)

Once login in to VM , gave D365 account to Admin user provisioning. That is successfully done.

Then go to IIS > Sites > AOS service > Manage > Browse

It’s asking for User name and password. I provided D365 account and password, Then it’s gave me an error

"There is a problem with Server

Sorry, the server has encountered an error. It is either not available or it can’t respond at this time. Please contact your system administrator"

Also find attached Image for reference.

Please let me know how to resolve this error.

Please give me more shed on this.
