Hey Usha, Please offer the following additional information to help us better understand and assist you in resolving your issue with receiving a null token when connecting to Microsoft Dynamics 365:

the framework or programming language you are using to connect to Dynamics 365.

the precise code or code snippet you're employing for token retrieval and authentication.

any stack traces or error messages you encounter when attempting to get the token.

Information on how Dynamics 365 is configured, including the version and any customizations or add-ons you've used.

Verification that you gave the appropriate permissions and correctly registered your application in Azure Active Directory.

I can help you more specifically if you give me these specifics.

Hello Usha,

When attempting to connect to Microsoft Dynamics 365, if you receive a null token, there is a problem with the authentication procedure. The following are some potential causes and remedies:

Check that you submitted the right client credentials (client ID and client secret) when you requested a token.

The token might have run out of time if it returns null or with an error. Repeat the authentication procedure to request a new token.

Make sure you're using the appropriate authentication process based on the OAuth 2.0 grant type you choose when registering your application.

Verify whether the registered application has the right access rights to the Dynamics 365 API.

Verify that your application can connect to the Dynamics 365 server without being hindered by network or firewall constraints.

Hello,

The error suggests that there is a problem with verifying the security of the message, so it can be seen as a security-related issue.

If you have verified the endpoint URL used to connect to Dynamics 365 is correct and up-to-date, Check security settings: ensure that the security settings of your Dynamics 365 instance and the XRM Toolkit configuration are compatible. Also verify that the appropriate security protocols, such as SSL and TLS, are enabled and configured correctly.

You might also need to make sure that the user account or service account used for connecting to Dynamics 365 has the necessary permissions and privileges to access the desired resources by verifying permissions
Firewalls might also be a blocking agent that you have to look into, so you might want to enable detailed login in the toolkit in order to trace the effect.

I hope this helps you. Let me know if it does
