OdataLink Error Code 8001: MYOB denied access to the endpoint
Error 8001 will be logged when MYOB denies access to the endpoint.
MYOB does further authentication based on the MY.MYOB user used when adding the data file. As such, it is possible that this user does not have access to all parts of MYOB.
In addition, some data files require setting an explicit data file USER NAME and PASSWORD. (e.g. Administrator).
Alternatively, you may remove and re-add the data file.
