Model Data Training showing error Network Unreachable in log file

[pkanetkar]

I followed following tutorial to train the model with my data.
https://github.com/IBM/MAX-Text-Sentiment-Classifier/tree/master/training

When I run command
python train_max_model.py max-text-classifier-training-config.yaml package
I get following error in file training-log.txt.

Do I need to change any thing in services of cloud IBM, do I need to open any port or something. Please help to solve this issue. I could not find help anywhere.

Thanks
