 [[https://en.wikipedia.org/wiki/QUIC|QUIC]] runs a stream-multiplexing protocol over Transport Layer Security (TLS) on top of UDP instead of TCP. Be sure you've enabled the port with both TCP //and// UDP. Most of the time, TCP 443 is enabled.

 ==== Possibly Google Chrome has not enabled QUIC by default ====
-At some point we noticed that Google Chrome decided to temporarily disable QUIC by default. Some users explicitly have to enable QUIC under ''chrome://flags''. This may not be the case for you, but it's a good idea to check whether QUIC is enabled in Chrome.

+==== Possibly bad cached SSL certificates ====
+Sometimes, especially when the site in question has encountered an SSL/TLS error before, Chrome will save the certificate in cache and cause QUIC to be unable to establish a connection. In this case, it can simply be fixed by clearing the browser cache.
