StanfordCoreNLP Server not responding

I am trying to run a very basic example as mentioned in the documentation, the CoreNLP server starts and is listening but nothing happens after it. I am not sure how to debug this.

Here is the code I am running:

import logging

from stanfordcorenlp import StanfordCoreNLP

nlp = StanfordCoreNLP(r'/Users/samarthbhandari/AuralAnalytics/text_metrics/textmetrics/stanford-corenlp-full-2018-10-05', quiet=False, logging_level=logging.DEBUG)

sentence = 'Guangdong University of Foreign Studies is located in Guangzhou.'
print('Tokenize:', nlp.word_tokenize(sentence))
nlp.close()

Here is my output log in DEBUG mode:
