SSL: CERTIFICATE_VERIFY_FAILED

Hello,

I must be overlooking something obvious !

I used notepad++ to edit default.cfg

I copy pasted apikey and secret from Poloniex, I get the following messages:

Thanks

cmd output —

Hi, I know it’s out-dated issue. I have same problem and here’s how i fix it.

python 2.7.14 window server 2016

poloniex use globalsign for ssl certificate. so I copy and paste globalsign’s root certificate into python’s cacert.pem file.

here’s link for globalsign

and here’s python script to check where your cacert.pem file is. from requests.utils import DEFAULT_CA_BUNDLE_PATH; print(DEFAULT_CA_BUNDLE_PATH)

@Evanito I would not add this, bypassing ssl certificate should only be done by someone understanding the risks. The ssl fail is a local configuration issue, not a Bot issue -> no code change.
