Trigger the splash screen manually
Loading http://nossl.sh gives access points the HTTP handshake they require to reveal captive forms or voucher prompts.
If you are stuck on a looping login, compare headers to confirm whether a proxy or VPN is still enabled.
How support teams use the data
Help desks capture the request snapshot and share it with network admins. The consistent layout keeps troubleshooting quick during peak check-in hours.
- Record timestamps of login attempts.
- Identify user agents that portals might block.
- Verify if custom DNS resolvers are interfering.
Will this page complete my authentication?
nossl.sh does not authenticate you, but it reliably launches the captive portal so you can sign in.
Can I share the counters with hotel staff?
Absolutely. The counters provide neutral evidence that many guests successfully reach the site.
