Fail to download index data through proxy setting

[zzj99-quant]

Describe bug

When downloading S&P 500 index, the proxy is not working. However, for individual stock (e.g. AAPL), proxy setting is okay.

Simple code that reproduces your problem

python sp500 = yf.download('^GSPC', start='2024-01-01', end='2024-02-01', proxy=my_proxy)

Debug log

1 Failed download:
['^GSPC']: YFTzMissingError('$%ticker%: possibly delisted; no timezone found')
