我在 Ubuntu 19.04 上遇到了一个奇怪的互联网连接问题。我的网络服务提供商不断拒绝它并且它是随机发生的，我也在办公室网络上遇到了这种情况。很多时候，每当我导航到某个网站时，我都会chrome立即收到错误：
This site can’t be reached
www.linuxbabe.com unexpectedly closed the connection.
Try:
Checking the connection
Checking the proxy and the firewall
ERR_CONNECTION_CLOSED
几秒钟后，页面内容突然被加载并显示出来。
我访问的几乎所有网站都发生了这种情况，我无法弄清楚哪里配置错误。
更新：如果我安装了守护进程，似乎就会发生这种情况trickled。我的trickled配置（/etc/trickled.conf）：
# this file is an example for a system-wide or personal settings file
# for trickle (see manual pages for trickle, trickled and trickled.conf
# below are two examples that should be self-explaining
[ssh]

有任何线索表明我是否存在任何配置错误吗？
