Connecting Phython interface to Eikon

After run this python script :

import eikon
eikon.set_port_number(9000)
eikon.set_app_key("...")

("..." is replaced by the key generated inside Eikon)
Python writes me this :

2020-08-20 14:30:55,348 P[6728] [MainThread 16184] Error: no proxy address identified.

Do you have any idea, how can i solve this problem?

Hi Gurpreet,

As per client-

It is what i currently find on the my port 9000 (going at http://localhost:9000/ping?all) :

{"port":9000,"mode":"eikon4","pid":14628,"hasSecure":true,"startedTime":"Tue Aug 25 2020 16:34:46 GMT+0200 (Paris, Madrid (heure d’été))","subApps":[{"path":"/heap"},{"path":"/ping"},{"path":"/sxs","data":{"hasSecure":true,"sxsApps":{}}},{"path":"/api"}]}

And my file .portInUse is also on port 9000.
