+ | ===== 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, specially when the site in question encountered a SSL/TLS error before, Chrome will save the certificate in cache and cause QUIC unable to establish connection, in this case it can simply fixed by clean browser cache. |
