Connection test

We check whether this network allows Quizhat live games. If something isn’t working, take a screenshot of this page (or copy the result) and send it to your IT department.

Testing…

It only takes a few seconds.

Site reachable (HTTPS)Quizhat pages and data on port 443
Live connection (WebSocket)The fast channel for live games
Alternative connection (HTTPS events)Used automatically if WebSockets are blocked
Backup connection (HTTPS requests)Used automatically if events are also held back by a proxy

For the IT department

Quizhat only uses HTTPS on port 443. Allow (also as *.quizhat.app):

quizhat.app · the site, the games and the live connection (wss://quizhat.app/live and https://quizhat.app/live/…)
www.quizhat.app · redirects to quizhat.app
stats.quizhat.app · anonymous visit statistics, no cookies

Live games use a WebSocket on wss://quizhat.app/live. If a proxy blocks it, Quizhat automatically switches to a connection over plain HTTPS (/live/sse, server-sent events, and /live/poll, /live/send): it works, but it’s slightly less responsive. For the alternative connection, the proxy must not buffer streaming responses (text/event-stream).

Only quizzes with videos also need www.youtube-nocookie.com and the YouTube domains. No software to install, no ports other than 443.
