Weird popup on every boot (Gnome & Arch)

So every boot I get a popup once the network comes on line. Header shows Index of and shows the following:

Index of /

Apache/2.2.15 (Red Hat) Server at nmcheck.gnome.org Port 80

Attached is a screenshot. I just want to stop it from popping up all the time. I am not finding anything via googlefu.

Arch linux (Antergos) with Gnome

what is the contents of your /etc/NetworkManager/NetworkManager.conf?

Its just stock conf, nothing enabled.

~> cat /etc/NetworkManager/NetworkManager.conf 
# Configuration file for NetworkManager.
# See "man 5 NetworkManager.conf" for details.

Do you have an extensions enabled that are supposed to check network status?

No no network monitoring or monitoring in general extensions.

Do you have a second account that you can try? Might help narrow down to user config or machine config

I can create one. What file would you need to compare?

It's just the bounce site for Gnome network manager connectivity check. If you don't want it, kill nmapplet, it will remov ethe networkmanager applet in the top bar, but it won't check connectivity at startup any more.

I had this issue today on Fedora. It has to do with OpenDNS settings. Review your block rules if you use so. Or try other DNS server for connectivity.

Only thing i had different on this box then the others was a bridge. I had this setup so my VM for PCI passthrough got a local ip from the DHCP server. I deleted the bridge and network profile, then created a new profile. I didn't create another bridge. Issue no longer occurs. Not sure if that was the root cause though, I have been using that bridge for a long time, this just started to happen since January.
