Before you open nossl.sh
Turn off Private Relay, disable VPNs, and forget any stale network profiles. Then join the Wi-Fi again.
What to look for on the page
Check that the status shows “Unsecure connection.” If it reports HTTPS, your phone may still be tunneling traffic.
- Confirm the IP matches the venue range.
- Tap copy to send headers to support.
- Reload after login to ensure the scheme flips to HTTP.
Do I need to disable content blockers?
Temporarily disable Safari content blockers until after you authenticate—they can block captive scripts required for login.
