HTTP operation failed with statusCode: 403


I have weekly reporting tool running to retrieve project data from FreeAgent to generate reports. It has been working before but since last week the retrieval of all projects is giving the following response:
HTTP operation failed invoking with statusCode: 403

I am making the exact same call from a local environment and this is working normally. Can it be that FreeAgent firewall has somehow identified the connection as malicious and therefore blocking the calls? If so, is there a way to discuss this as I understand there is a cap on the amount of requests but now it makes it very hard to use for automation purposes.

Any help is appreciated very much!

With kind regards,
