I am trying to follow @ChrisHemedinger's article on web scraping at https://blogs.sas.com/content/sasdummy/2017/12/04/scrape-web-page-data/
I can access the web site mentioned in the following code via my web browser, but the code returns an error.
563 filename src temp; 564 proc http 565 method="GET" 566 url="https://www.unitedstateszipcodes.org/14068/" 567 out=src; 568 run; ERROR: Error connecting to 220.127.116.11:443. (The connection has timed out.) ERROR: Unable to connect to Web server.
I am guessing that the error is because my company's firewall prevents this type of HTTP access, but that's a guess. What do you think? Are there other possible causes of this error?
I tested it under SAS On-Demand Academic ,
