Temporary failure in name resolution

Thank you you're reply,

log

This process collects information from your Pi-hole, and optionally uploads it to a unique and random directory on tricorder.pi-hole.net.

The intent of this script is to allow users to self-diagnose their installations. This is accomplished by running tests against our software and providing the user with links to FAQ articles when a problem is detected. Since we are a small team and Pi-hole has been growing steadily, it is our hope that this will help us spend more time on development.

NOTE: All log files auto-delete after 48 hours and ONLY the Pi-hole developers can access your data via the given token. We have taken these extra steps to secure your data and will work to further reduce any personal information gathered.

^ Please note that you may have more than one IP address listed.
As long as one of them is green, and it matches what is in /etc/pihole/setupVars.conf, there is no need for concern.

The link to the FAQ is for an issue that sometimes occurs when the IPv6 address changes, which is why we check for it.
