Cloudflare does not work on some free wifi

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.

It sounds like you’re using the 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?
