I cannot obtain the timeseries of the instrument 'C-STKOKL-2-EIA' . It worked fine for years but since the last few days I have been getting :
ERROR:pyeikon:Backend error. 400 Bad Request
ERROR:pyeikon:HTTP request failed: EikonError-Backend error. 400 Bad Request.
The same code works fine for some colleagues so it looks like it is a problem related to my account specifically.
