2 days ago, my eikon through python stopped working, showing only the error message: Error code 500 | Server Error: Internal Server Error

2 days ago, my eikon through python stopped working on my machine with no apparent reason, showing only the error message: Error code 500 | Server Error: Internal Server Error - {"code":500,"message":"getaddrinfo ENOTFOUND emea1.apps.cp.thomsonreuters.com emea1.apps.cp.thomsonreuters.com:443","statusMessage":"Internal Server Error"}; using python 3.6, eikon python package 1.1.4, eikon desktop 4.0.52

Then I could check that the APIPROXY is running properly with curl:

C:\Windows\system32>curl http://localhost:9000/ping?all

{"port":9000,"mode":"eikon4","pid":15688,"hasSecure":true,"startedTime":"Thu Sep 10 2020 15:53:24 GMT+0200 (W. Europe Summer Time)","subApps":[{"path":"/heap"},{"path":"/ping"},{"path":"/sxs","data":{"hasSecure":true,"sxsApps":{}}},{"path":"/api"},{"path":"/sxs/v1/services/messenger"}]}

I also tried the handshake test that is proposed in the link you sent, but that does not look good.

C:\Windows\system32>curl http://localhost:9000/api/handshake

Temporary Redirect. Redirecting to http://localhost:9060/api/handshake

C:\Windows\system32>curl http://localhost:9060/api/handshake

{"code":404,"message":"Not Found","statusMessage":"Not Found"}

from the APIPROXY logs:
