The restore of the Database in Dev environment is completed and followed all the required steps (I have already restored DB once without any errors).

Now after the Dev restore, I'm not able to open my Dev environment. Error : Sorry, we lost the connection temporarily. Please be patient while we reconnect you.

And restarted the IIS services and getting error : Metadata service communication retry attempts failed to resolve issues with the following settings AX7CertificateUserName: FRServiceUser@dynamics.com; AX7CertificateThumbprint: ; AX7FederationRealm: spn:; AX7ProviderName: https://mintedtoken.dynamics.com; AX7TokenIssuer: https://fakeacs.accesscontrol.windows.net/ Component: Microsoft.Dynamics.Integration.Common.TraceLog User: NT AUTHORITY\NETWORK SERVICE Machine: SIG-ERP-DEV-1

Tried all the possible ways and still dev environment is not working.
