How to install docplex package in Anaconda?

Question

I'm trying to install docplex on a work computer and was wondering where the error is coming from when I try to install it.

I'm using Anaconda3-5.2.0 and Python 3.6.5.final.0. I'm running anaconda prompt and typing in the following code:

conda install -c ibmdecisionoptimization docplex 

I get this error after I type it in:

CondaHTTPError: HTTP 000 CONNECTION FAILED for url https://conda.anaconda.org/ibmdecisionoptimization/win-64/repodata.json Elapsed: -

An HTTP error occurred when trying to retrieve this URL. HTTP errors are often intermittent, and a simple retry will get you on your way. ConnectionError(MaxRetryError("HTTPSConnectionPool(host='conda.anaconda.org', port=443): Max retries exceeded with url: /ibmdecisionoptimization/win-64/repodata.json (Caused by NewConnectionError(': Failed to establish a new connection: [Errno 11001] getaddrinfo failed',))",),)

I expect the terminal to install the package, but it's giving me an error message. I tried doing a pip install and that did not help either. Please help, thanks!
