@Ekliptor can you confirm that you have the most recent version of CCXT?

[Ekliptor]

Yes.
console.log(ccxt.version); ccxt prints 1.18.1281

nodeJS v12.11.1

[kroitor]

@Ekliptor ok, thx! We will debug this and will get back to you ASAP.

Bitstamp has fixed this on their side, so it's now a proper HTTP rejection code if the user location is blocked, closing this for now. Feel free to reopen it or just ask further questions, if any.
