Chrome 67 and captive portal at 1.1.1.1

Using 67 stable, Google Pixel 2XL and also Windows 10. Chrome decides to redirect http://1.1.1.1 to https which means I can no longer access my company's guest wifi portal. I realize this probably stems from the fact that 1.1.1.1 is now a legit site but Chrome should check for captive portals before redirecting to the CloudFlare DNS site.
 
On my Windows PC I can use another browser as a workaround but on my phone I cannot do that.

Hi Sava, 

Thanks for posting on the Google Chrome Help Forum.

Could you confirm if you’re on a domain or a managed system? If yes, are you the administrator? If yes, please let me know and I’ll have this post redirected to the appropriate forum for further assistance.

If you're not the administrator, then please get in touch with the domain administrator for further assistance.

Keep me posted.

Regards,
Pearl

We're seeing the same issue, we're a public library and are getting more and more reports of user access to the captive web portal having issues and getting net::ERR_CONNECTION_REFUSED when redirected to 1.1.1.1, this is only affecting Android and Chrome users.  Would be nice to get a fix from Google on this so we don't have to re-engineer our whole wireless network to fix the problem.

Same here, having issues with Chrome 67 and the cisco captive portal at 1.1.1.1.  If anyone has a fix, that would be greatly appreciated!  Thanks!

We were able to fix this issue by changing the captive portal IP address to something other than 1.1.1.1.  We used 192.0.2.1 which was a recommended IP address from Cisco.  It would still be nice for Chrome to work with 1.1.1.1 as our fix was a workaround.  You can check out RFC5737 for more details on the 192.0.2.0/24 network.  https://tools.ietf.org/html/rfc5737

Cisco TAC provided our organization the same workaround. Chrome on mobile and windows redirects correctly. Firefox, IE, Edge on windows also. However, I have had an issue during testing in which safari on iOS 11.4 would not redirect to the new IP. Dumped cached, restarted, and forgot network and it has persisted. I’m wondering if anyone else has seen this after changing the portal IP
This is halting us for now.
 
I would like to note that having to reboot the controller(s) is going to cause a ton of work to avoid downtime.(Migrating APs to backup/alternate WLCs)
Cisco tech remarked that “Google is working on it..”
This makes me curious if there is some change coming to Chrome. I’d have to say I’d be irritated if all of this was for a temporary situation.

Lester:

Were you able to add the External DNS record as suggested above for your portal?
