HTTP Request Failed ConnectError ('[SSL: WRONG_VERSION_NUMBER]')

ryan_choi

I have set my proxies and gone through the troubleshooting article: https://developers.lseg.com/en/article-catalog/article/eikon-data-api-python-troubleshooting-refinitiv?secureweb=RefinitivWorkspace

I still can't figure out what is the issue here and I'm already on my second app key

Here are some further logs:

2025-06-09 11:37:40,141 P[23400] [MainThread 23428] Init a Desktop session with new app_key

FYI:

http://127.0.0.1:9007/api/status is shows me this:

{"statusCode":"ST_PROXY_READY","version":"3.11.0"}

So I know 9007 is the correct port it should be connecting to

@ryan_choi

The legacy Eikon data API won't be supported for long, and you will have to migrate to newer libraries. Most of the APIs are backwards compatible, so there should not be much change in the application code.

I think, the local connection to the API proxy is also being sent through your corporate proxy. If set - please unset the command line variable HTTP_PROXY and HTTPS_PROXY and try again.

Hello @ryan_choi

Can you please provide more information about your setup. Are you using LSEG Workspace with latest LD Library? Do you have a Corporate system proxy setup? Is this proxy setup as environment variables on the command line?

The SSL error should not come into play here - it is not an https connection.

ryan_choi

I am using a corporate system proxy setup with LSEG workspace, but thr LD library unfortunately cannot be installed due to an issue installing metadata numpy in the lseg-data package which is odd. I have set up the environment variables in my code under HTTP_PROXY, HTTPS_PROXY, http_proxy, and https_proxy. Right now, I am currently using the Eikon Data API. However, several weeks ago I was able to get a connection using Eikon Data API and go through the tutorials such as getting the ISIN # for some symbols.

I set the proxy like this:

os.environ['http_proxy']=….

Ok I see. I unset the corporate proxy and it now works. Thank you so much!
