Quandl HTTPS Protocol Issues

Hello All,

Quandl recently deprecated an older version of HTTPS which the live trading environment is currently using. This is causing some live algorithms to work in backtesting but not return data in live trading.

The pinned version of Mono we use in live trading is more stable and has fewer memory leaks than later versions of Mono, so we have been reluctant to upgrade it in the live environment. We're doing research and testing and if the newer versions of Mono are stable and we will deploy it to the community in live trading once it is validated.

We have made a workaround which will be applied automatically to new deployments of LEAN. If you have an existing algorithm with Quandl data we highly recommend stopping and restarting your algorithm.

Best,

Jared
