Hello @kalaimani_padmanabha @nawal555

Can you tell me which version of Python are you currently running on and the device from which you are accessing?

12

at my end python version is Python 3.12.4 and running Python code over HP pavilion windows 10

13

Also, can you check Can you check SSL version with:

openssl version

in terminal?

14

hi Hardick … below is my version.
OpenSSL 3.3.2 3 Sep 2024 (Library: OpenSSL 3.3.2 3 Sep 2024)

15

@nawal555

I am also on 3.3.* and it is working for me. Anyways, can you try with import ssl in your code at beginning?

16

Workaround can be by disabling it, not recommended

import ssl
import certifi

ssl._create_default_https_context = ssl._create_unverified_context

17

hi Hardick,
Tried but still its not working and tried with Tushar suggestion too…but with no luck…
[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1000)

18

you can try installing certifi and force python to use those certificates

import ssl
import certifi

ssl._create_default_https_context = ssl.create_default_context(cafile=certifi.where())

19

no Tushar Its also not working …I tried yesterday as well and today also …
My historical data is working but only live feed is giving such errors …any other clue …
