• the IP address making the request
• the IP address being connected to
• the complete URL requested
• the date, time, and timezone for the request

The web servers headers are called “response headers” because web servers send an “HTTP …

However, I’m fairly certain that the issue is going to be a DNS lookup issue. If so, the questions from that section will be the ones we need the answers to in order to be able to troubleshoot this.

​Please let us know if there are any questions for us.
