Please be informed that the resolution posted in the support ticket is as the below

Even though the HTTP request is directed to the localhost, your HTTP proxy intercepts it. After intercepting the request, the proxy returns the request to your machine, but now to Eikon API Proxy, the request appears as coming from a remote machine (as it comes from the IP address of the HTTP proxy). Eikon API Proxy rejects the request with the error message that you've seen because it only allows requests coming from the same machine.

The client need to configure proxy settings to allow HTTP requests directed to the localhost to not be intercepted by your HTTP proxy 

ERROR:pyeikon:Error on handshake url http://localhost:9000/api/handshake : EikonError(1, 'Status code 400: App key is incorrect')

Hi @rayr.hou ,

To access Eikon Data API via Jupyter Notebook, you need to connect to the API using the APP key. APP key can be generated via APPKEY Generator app (type APPKEY in Search box) within Eikon/Workspace.

After you have an API key you can connect to the API using the query below

import eikon as ek
ek.set_app_key("YOUR APP KEY")

In the example above I have put the APP key directly in the code, however for security purposes you may want to read the APP key from a local txt file, config file or an environment file.

Hope this helps, please let me know if you have any further questions.

Best regards,

Haykaz

Hi Haykaz,

I ran the same code you provided with my APP key.

The errors are shown as below

2022-12-12 13:27:20,774 P[19800] [MainThread 19804] Error on handshake url http://127.0.0.1:9060/api/handshake : EikonError(1, 'Status code 400: App key is incorrect')
2022-12-12 13:27:20,775 P[19800] [MainThread 19804] Error on handshake url http://127.0.0.1:9060/api/handshake : EikonError(1, 'Status code 400: App key is incorrect')
2022-12-12 13:27:20,776 P[19800] [MainThread 19804] Port number was not identified, cannot send any request

I can confirm the app key is correct as it runs perfectly in codebook

Hi @rayr.hou ,

Do you have eikon/workspace running on the background? It should be open to connect to Eikon API via the desktop session.

Best regards,

Haykaz
