Eikon Data API session hanging

I got a very strange problem running Eikon Data API application.

The session hangs at specific time at 12:00am. 10:00am, 12:00pm (Sydney time zone). and the session is blocked from that point.

The requests sent in these periods are normal, and they worked fine after session was restarted

The API error logs showing error like this

[2022-07-22 10:00:34,204;s] - [ERROR] - [_check_server_error] - Backend error. 400 Bad Request

[2022-07-22 10:00:34,220;s] - [ERROR] - [send_json_request] - HTTP request failed: EikonError-Backend error. 400 Bad Request

When session is blocked, the response from API shows error like this

2022-07-18 13:15:33,372 - qykit.eikondata - ERROR - eikon data api request get_data failed: Error code 401 | Eikon Proxy not running or cannot be reached. Please read the documentation on troubleshooting

Hi @jason.huang ,

May I ask if you use the script to restart Eikon Desktop during the time that the error occurs?

as I saw the question posted here and the error 'Error code 401 | Eikon Proxy not running or cannot be reached. Please read the documentation on troubleshooting', the suggestion for this error was suggested by my colleague as below.

Double-check that you are running your python code on the same physical machine where your Eikon/Workspace is running. Eikon proxy is part of your desktop.

See Eikon Data API Quick Start guide for Windows on how to create your valid API Key.

If the issue persists, review article Eikon Data API(Python) Troubleshooting | Refinitiv for the steps to troubleshoot.

Hope that this information is of help

I restart the Eikon at midnight 12:00am. It is up for the whole day. And the python app on Eikon Data API is running on same host, and it works fine to retrieve data other than these several specific time.

If the API key is invalid, it won't work at all. Not my case

aramyan.h

I have learned that the case is resolved with the following answer:

Advised to downgrade to httpx version 1.14.2 using the following commands.
-pip install httpx==1.14.2 (if you are an admin)
-pip install https==1.14.2 --user (otherwise)

Could you please accept if the issue is resolved, otherwise post another question if the issue still exists.
