不管是连接不上该站点还是连接时间过长一般都是IPV6网络问题
用随意编辑器(nano。vim。vi,emacs)打开/etc/gai.conf文件
找到
#
# For sites which prefer IPv4 connections change the last line to
#
# precedence ::ffff:0:0/96 100
然后取消最后一行的凝视得到:
#
# For sites which prefer IPv4 connections change the last line to
#
precedence ::ffff:0:0/96 100
这样IPV6依旧是打开的,可是会优先使用IPV4。这样问题就解决啦!
