Container pulled from NGC results in 502 Bad Gateway


#1

I pulled the docker container image from NVIDIA GPU Cloud to my local server with GPU based on instructions here:
https://ngc.nvidia.com/catalog/containers/partners%2Fdeep-learning-studio

I used the following command to pull it.
$ sudo docker pull nvcr.io/partners/deep-learning-studio:cuda9-2.5.0

I was able to run the container successfully with the following:
$ sudo nvidia-docker run -d --rm --name deep_learning_studio -p 8880:80 -p 8881:80 -p 8888:8880 -p 8886:8888 -p 8889:3000 -v $HOME/dls/data:/data -v $HOME/dls/database:/home/app/database -v $HOME/dls/keras:/root/.keras -e DLS_EULA_AGREED=y nvcr.io/partners/deep-learning-studio:cuda9-2.5.0

However, I got the error message below when I accessed http://(IP address):8880:

502 Bad Gateway
nginx/1.10.3 (Ubuntu)

Am I missing something?
