It Doesn't do the captive portal

[SalvatoreFerro]

I have followed all the tutorial, but the wifi doesn't autoredirect on a wepage

Did you do the iptables steps correctly? Mine didn't redirect at first and was caused by an error I made here.

I have the same Issue, but only with my Phone. If i connect to the open wifi on my Win 10 Laptop it immediately redirects me to the website.
Note: I am not using a node.js server but a python flask server, and i just redirect all uncought routes to the domain i want it to be called, which workes just fine. But on my phone, literally nothing ever happens. If i connect to open hotspots at airports for example, it just works. On my website i get /connecttest.txt requests when using my laptop, which it happily redirects to raspberrypi.local in my case. On my phone, nothing appears to happen at all, any ideas on how to fix this?
