Connectivity-check is not working

Yes it works on ubuntu with same dns setup… I just check that.

If i am logged out in ubuntu it show me a ? Mark with the wifi icon on top and ask to login but in fedora i did not the that ? In wifi icon i think fedora does not do the connectivity check. Though it says but it does not.
I find ubuntu uses this domain for connectivity check but i don’t know about fedora.
connectivity-check.ubuntu.com

it download a text file
http://fedoraproject.org/static/hotspot.txt
file should contain OK

Maybe i don’t know but i find this that ubuntu use this and just when i remove the ethernet of my wifi router ununtu top bar shows the wifi icon with a ? Mark but fedora does nothing and also if i log out my ubuntu asks to log back in and give a notification comes but in fedora there is no such thing. I really don’t know if i am loged in or not as i use ungoogled chromium build i have to ping my public ip to get the login page and login it is annoying so i think it is a bug in fedora. I am use.
