We have successfully created an application with Companies House and generated a Web key to access the APIs.
However, when initiating the OAuth web server flow using our Client ID, we are encountering the following error: “Sorry, there is a problem with the service.”

Could you please assist us in troubleshooting this issue?
After calling the OAuth2 endpoint in the sandbox environment, I was redirected to the Companies House sign-in page. Since I didn’t have an account initially, I created one using GOV.UK One Login.
