I have been attempting to stream the IEX market data following the documentation from the alpaca-trade-api package. I have been receiving the following error:

[SSL: CERTIFICATE\_VERIFY\_FAILED] certificate verify failed: certificate has expired

I have:

- Deleted the DST root certificate in the venv and on my system
- Deleted any old certificates on my system (hard to check with certifi)
- Deleted and re-downloaded all of my library in the venv including certifi

I am running on windows 10 and Python 3.7. Any additional solutions?
