Cloudflare does not work on some free wifi

Hello,
I am a new member,
I have issues using cloudflare on some free wifi connections, when I try to connect to the free wifi some free wifi connections will not connect to the free wifi.
Any help to fix this would be great.
Thanks

It sounds like you’re using the 1.1.1.1 app, and those free wifi hotspots use a captive portal for you to check in to the free wifi. I know there are some captive portals that the app struggles with.

Out of curiosity, if you turn WARP off, then log into WiFi, does it work if you turn WARP back on?
