I discovered this issue while on holiday in Italy, but it's not working in public places at home either.
What is the reason I'm first directed to http://connectivitycheck.platform.hicloud.com instead of the login page?

Finally, I have tried this and it's work for me :
Go in the setup, Wifi & Network when Wifi is Off, you can view and change Private DNS settings from :1dot1dot1dot1.cloudflare-dns.com to automatic. Save. Put the Wifi On. It should work now.
Let me know if it works also for you.
