Some problems when downloading data

[DicksonWallace]

Hello, when I use the investpy to download data, I found that without a vpn, I cannot connect with the investing.com and there's a 503 error. And when I turn on vpn and adjust it to the global mode (all connections go through the vpn), there's still some error like:
Traceback (most recent call last):
