Hi,
I have conducted a web page test and visited cnn.com:
https://www.webpagetest.org/result/170427_0T_1N2F/
The _ip_addr field is missing for all HTTPS requests in the HAR file. The _client_port field is also set to 0 for all HTTPS requests. These fields are available for HTTP requests.
These two fields were available for all requests a few weeks ago.
Thank you
