Hello,
I think this problem appeared after I deleted the folder “flatpak” from my disk (since it used more than 10Gb and I don’t use flatpak). I don’t about the network functionalities, but Internet is working fine (just the wifi signal is always showed as interrogation point instead of the signal strength).
Every time I start up the laptop, I have the following window:

Thank you for any help you can provide 
I have the same problem yesterday on Computer Desktop and Thumbleweed, whenever I start my computer, that annoying window appears.
The connection works well, I’ve already tried to delete the connection without result, or sometimes reset the shell, which has become unstable since the last updates, reset even when Firefox closes.
There is an open and never closed

Hi
Your not using openSUSE…?
openSUSE uses conncheck.opensuse.org not nmcheck.gnome.org
cat /etc/NetworkManager/NetworkManager.conf
[main]
plugins=ifcfg-suse,keyfile
[connectivity]
uri=http://conncheck.opensuse.org
I’m taking a video to see what happens every time I start Thumbleweed , removing the connection and creating a new one

Hi
I can’t duplicate with Tumbleweed (no h 
) 20171010 GNOME 3.26.1. I connected to a never used before connection, no popup web page, connected and was able to surf the net etc…
If you create a test user, does it duplicate?
I’m guessing some sort of mime issue (maybe with FF 56?), but why it’s going where it is… if you fgrep in your home folder;
cd
fgrep -r "nmcheck" *
Any hits?
I tried with a new user the popup continues to come out.
I have Firefox 56, and even with a new profile the popup is always there
Hi
So if you browse to;
http://nmcheck.gnome.org/check_network_status.txt
It should say “NetworkManager is online” which is an error (it should return nothing);

I have no idea what is calling it… maybe a frgrep through the system directories, maybe a funky systemd service?
Temporarily disable Network Managers connectivity check to see if it still happens??
Add
interval=0
to the “[connectivity]” section of “/etc/NetworkManager/NetworkManager.conf” and reboot.
It worked:)
thank you
Hi
You didn’t add an entry in your /etc/hosts file did you?
OK…
If you want to make that a permanent change that won’t get overwritten by future updates, then create a file named (for example) “50-disable-connectivity-check.conf” in “/etc/NetworkManager/conf.d/” with the contents:
[connectivity]
interval=0
Perfect, now the icon no longer has the?
But it is not possible to add solved to the post title
Hi
Nope, we don’t solve anything Anyway with discussion on the factory mailing list, it would appear it’s related to ipV6 vs ipV4 (which is what I use) and captive portals.

Thank you for the reply .
While using Opensuse for more than 10 years I have never opened a Bug Report … I do not even know how to do it.
Perhaps now that I learn
Ciao
