404: resource not found

We are getting a 404 resource not found error as shown in image.

The error message is: https://api.freeagent.com/v2/bank_accounts api
request to this end point is not showing all accounts. There should be 2
but showing only 1’

When I am logged in to FreeAgent I can view information of the missing
account and when we try with the api request we get “resource not found”

Please note I am not a developer and hope the above makes sense. I can
forward any questions to my developer.

Thanks for any help you may be able to provide.
