Eikon Python API Error code 503

Hi,

I tried the following code:

import eikon as ek

ek.set_app_key(my_app_id)

ek.get_data(instruments = 'BD4LHL9', fields = 'TR.RIC')

And it returned me the following error. Any ideas how I can fix this?

Apologies for the late reply as I happened to be away for the past week.

I got the following when I typed 'ping 10.190.168.137':

Pinging 10.190.168.137 with 32 bytes of data:

Not too sure with the proxy settings at my company, I'll check with my IT department first.

Hi,

Could you check if you have following dependency versions that cause issue in current version :

httpx 0.15.x or 0.16.x => need to downgrade to 0.14.3 (pip install httpx==0.14.3)
nest-asyncio 1.4.x => need to downgrade to 1.3.3 (pip install nest-asyncio==1.3.3)

(it supposes that you have eikon 1.1.6.post3)

Hi @pierre.faurelpierre.faurel,

I have downgraded both packages and am using eikon 1.1.6.post3. The code still does not work.

It used to work fine till recently.

Hi,

Sorry that didn't fix your issue.

Could you provide followed information ?

Eikon Desktop version
'pip list' result

If we don't identify the cause, the next step will be to activate the log in your script to have a full trace.

Hi Pierre,

Below is the requested info:

1. Eikon Desktop version: 4.0.52 (4.0.52055)

2. pip list result:

Hi,

All seems to be correct in your python env.

Could you clean Eikon cache then restart Eikon and retry to run python script ?
Another possible root cause : do you have any proxy/firewall that could change recently and block access to Refinitiv servers ?
To check this, could you open https://apidocs.refinitiv.com/Apps/ApiDocs (it will request your Eikon login/pwd)

Hi Pierre,

I clean the cache, restarted Eikon and reran the python script. The same issue still persists.
I could open the link you provided. In the API Playground I could GET https://api.refinitiv.com/data/historical-pricing/v1/views/events/VOD.L and retrieve a response and data.

Despite the above the python API still does not work.

Hi,

To investigate deeper, could you activate the log in your script to have a full trace ?

add environment variable: HTTPX_LOG_LEVEL=trace
add ek.set_log_level(1) in your script

then run your script and check errors in output.

Hi Pierre,

Here is the output towards the end where the 503 response is seen:

Hi,

Do you know where comes from the 10.190.168.137 IP address ?
Do you have any response on "ping 10.190.168.137" command (I have time out on my side) ?

Could you check if you have any proxy/DNS that manages refinitiv server address with fixed IP address ?

Apologies for the late reply as I happened to be away for the past week.
