Web-auth not automatically redirecting

[vikas01234das]

• When i connecting in my SSID, no automatic redirect to https://1.1.1.1/ But when i enter url https://1.1.1.1 with my hands everything is ok working !

1) ipconfig - correct

2) DNS resolving - correct

3) WLC-> controller -> interface -> Virtual -> ip address - 1.1.1.1 and DNS Host Name -> Empty 

• 4) When i reboot WLC - web-auth redirect not working.

Warning: do not use https redirection on a busy 9800 WLC.  We had it enabled and numerous clients were not getting splash/landing page at all.  TAC eventually told us to turn it off "NOT RECOMMENDED" and that solved all the problems.  No option to tune or optimise it and it turns out 9800 capacity for https redirection is less than 8540 and the WLC will just stop redirecting clients - even on http - causing severe degradation of service.
Do not use it on older AireOS WLCs and it is only scalable on 8540 or 5520 running 8.10 software.

Regarding @vikas01234das original problem - as I've explained many times before on this community:
Redirects to https pages will only work reliably on modern devices and browsers using a registered DNS resolvable fully qualified domain name (FQDN) with a matching certificate issued by a public CA which the devices trust.  Trying to use IP addresses (whether 1.1.1.1 - which you should not use - or anything else) WILL cause problems on the majority of modern devices and browsers.
