Bitso "Invalid Nonce or Invalid Credentials" error on certain Private methods

• OS: Windows 10
• Programming Language version: Python 3.6
• CCXT version: 1.10.810
• Exchange: Bitso
• Method: fetch_order

I’m getting an “Invalid Nonce or Invalid Credentials”. Though this does not happen when I try to fetch my balance or when I create an order. Note the only private methods that seem to work for Bitso in the ccxt library are create_order and fetch_balance. cancel_order should be using privateDeleteOrdersOid. That I already fixed. But I’m not getting any further with “Invalid Nonce or Invalid Credentials” error. Any ideas?
