error code 500

Hi
I'm trying to connect the python data api from spyder 3.3.6.

Using Eikon API Version 1.1.8

When i try this simple request:

import eikon as ek

ek.set_app_key('my key')

df = ek.get_timeseries(["MSFT.O"],

start_date="2016-01-01",

end_date="2016-01-10")

I get the following error message:

2021-02-26 09:16:21,835 P[10184] [MainThread 19780] Error code 500 | Server Error: {"code":500,"message":"connect ECONNREFUSED 159.220.1.19:443","statusMessage":"Internal Server Error"}

2021-02-26 09:16:21,838 P[10184] [MainThread 19780] HTTP request failed: EikonError-Server Error: {"code":500,"message":"connect ECONNREFUSED 159.220.1.19:443","statusMessage":"Internal Server Error"}

Then i tried this code:

import eikon as ek

ek.set_log_level(1)

ek.set_app_key("my key")

state = ek.get_desktop_session().get_open_state()

if state == ek.Session.State.Open:

ek.get_news_headlines('R:LHAG.DE', date_from='2019-03-06T09:00:00', date_to='2019-03-06T18:00:00')

The output of this request, i postet in the following .pdf

Does anyone have a clue, how to solve this problem?

Thank you very much for your help,

best wishes
