 +===== Troubleshooting =====
 +
 +==== CloudFlare doesn'​t support QUIC yet ====
 +Please keep in mind that CloudFlare doesn'​t support QUIC yet at the time of this writing. If you are behind CloudFlare, please disable it before testing/​using QUIC.
 +
 +==== 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 ''<​nowiki>​chrome://​flags</​nowiki>''​. 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.
