text: Title: API Calls not working
  Body: I am not getting the expected response from Alpha Vantage APIs. The following are the details, could someone help?
  
  Infrastructure - GCP Windows server
  GCP Region: asia-south1-c
  Error - { "Note": "Thank you for using Alpha Vantage! Our standard API call frequency is 5 calls per minute and 500 calls per day. Please visit https://www.alphavantage.co/premium/ if you would like to target a higher API call frequency." }
  Key - Free trial keys
  
  Pls note our url /python code works well to fetch the details however through GCP infrastructure is not working. 
  
  Code: 
  
   def __init__(self, api_key, part_url, query, function, exchange, symbol, interval, format):
          self.api_key = api_key
          self.part_url = part_url
          self.query = query
          self.function = function
          self.exchange = exchange
          self.symbol = symbol
          self.interval = interval
          self.format = format
  
      def get_data(self):
          #data_url = 'https://www.alphavantage.co/query?function=TIME_SERIES_INTRADAY&symbol=NSE:TATAMOTORS&interval=1min&apikey=STPO0LS61SH9DZ0J&datatype=csv'
          data_url = self.part_url + self.query + self.function + '&symbol' + '=' + self.exchange + ':' + self.symbol + '&' + 'interval=' + self.interval + '&apikey=' + self.api_key + '&datatype=' + self.format
          print (data_url)
  
  try:
              data=requests.get(data_url)
          except Exception as e:
              print ("Failed with error {0}".format(e))
              raise SystemExit
