Business Central connection error

Hello all, I wanted to create a flow with Business Central connector(Cloud). For the very first time when I connected I was able to connect using the connector and create records. But now the connector is showing the following error inside flow.

Your user is not authorized to access this resource. Please contact your administrator. {"status":401,"message":"ErrorCode: Authentication_InvalidCredentials The server has rejected the client credentials.

 When I try to create a new connection, the same error comes.


 The following is the details of an existing connection.

Can anyone tell me what is happening with the connector?
The error is same even when I try from a different browser and machine.
Thanks in advance.


Hi Aswin,


My first thought looking at this error would be that it's possibly coming from Business Central.  Does your account have the appropriate permissions in Business Central to create these records?  Could your permissions have been changed?

Hi Tom, Thank you for your response. The account has a super user privilege in Business Central.

Hi Aswin,


Ok.  The message does say the issue is Authentication_InvalidCredentials, so I would recommend double/triple-checking that the credentials on the connection are valid,


It's also possible something like Azure Conditional Access Policies are preventing the connection from authenticating against Business Central correctly.

Thank you Tom,
The credentials are correct, we are able to login to Business Central, Power Automate, Power Apps using the same credentials.
I ll check Azure Conditional Access Policies as you mentioned.
