Hi I checked locally and I can access normally. Can you try to verify again? Or provide the following mtr or ping information Regarding the issue of GeoIP being displayed as China, because this IP address has only recently been used in California, the GeoIP data update takes some time. You can use a server located in California, USA to ping or mtr to verify the location HSTS or TLS issues, we tested it will not affect wget or curl, it only works on the browser, you can curl http on a server, you can access directly, and will not be prompted to be redirected http://mirror.lshiy.com/centos/timestamp.txt ____________________ Shucheng Li > 在 2020年9月23日，下午1:55，Fabian Arrotin <arrfab at centos.org> 写道： > > Hi, > > Our pre-flight check failed to validate that mirror (not able to > connect, maybe some firewall in between), which is also located (from > GeoIP lookup) in China, and not California,USA. > and FWIW, your main website enforce HSTS but with TLS issue, so not even > possible to browse it either. -------------- next part -------------- An HTML attachment was scrubbed...
