Describe bug
Hello,
using yfinance ==0.2.59 and python 3.3.13 I get an error message while running a line of code
Could anyone give me some suggestions? This issue came after the Rate limiting one: YFRateLimitError('Too Many Requests)
Simple code that reproduces your problem
yf.download(actifs_cad, start = last_day_of_last_year)['Close']
Debug log from yf.enable_debug_mode()
Error: CertificateVerifyError('Failed to perform, curl: (60) SSL certificate problem: self signed certificate in certificate chain. See https://curl.se/libcurl/c/libcurl-errors.html first for more details.')
