r error - Unknown SSL protocol error in connection to query2.finance.yahoo.com:443

Question

I am connecting to the query2.finance.yahoo.com in order to scrape some information from the google finance for 3000 stocks (written in json as shown here). I am able to retrieve information until, say 50 stocks or so, then it throws an error message saying:

Error in function (type, msg, asError = TRUE)  : 
  Unknown SSL protocol error in connection to query2.finance.yahoo.com:443** 

My guess is that the google team is block my server for suspicious activities for scraping information from their site, but I am not sure.

Revised full error message:

Error in function (type, msg, asError = TRUE)  : 
  Unknown SSL protocol error in connection to query2.finance.yahoo.com:443
