with the latest code of the cryptostore and cryptofeed

This error happens after I git pull the latest code and relaunch the cryptostore program

aio-libs/aiohttp#3535

it seems that it is a Python problem.

I am using python 3.7.3

[bmoscon]

The bug report seems to indicate you should upgrade to 3.7.4, but not sure if that will actually fix it or not

Not working with 3.7.4, still got 404

f = FeedHandler()
f.add_feed(Bitstamp(channels=[L2_BOOK], pairs=['BTC-USD', 'ETH-USD'], callbacks={L2_BOOK: BookRabbit(depth=1)}))
f.run()

I can sub with 'BTC-USD' pair, but the 'ETH-USD', 'XRP-USD', 'LTC-USD'... pairs got 404 error.

[bmoscon]

nothing i can do about this - it works for me, its likely an issue with your certs, isp, etc. Cryptofeed doesnt do any SSL handling directly, its all done via the 3rd party libraries it uses

The old version before 8c6aa44 commit works fine for me. probably has some bug in the 8c6aa44 commit.

Line 139 in 8c6aa44

urls = [f'https://www.bitstamp.net/api/order_book/{sym}' for sym in pairs]

The URL https://www.bitstamp.net/api/order_book is fine, but I can't get a response from https://www.bitstamp.net/api/order_book/ltcusd or https://www.bitstamp.net/api/order_book/ethusd, etc. I think this where the problem is.

The URL 'https://www.bitstamp.net/api/order_book/{sym}' should be 'https://www.bitstamp.net/api/v2/order_book/{sym}' for the alts pair, the URL
https://www.bitstamp.net/api/v2/order_book/ltcusd work as expected. I will create a pull request to fix this.
