一直在和我家用服务器上的一个奇怪问题作斗争：Docker 容器一开始能正常运行几个小时，然后容器内部的网络就会突然失效，但宿主机仍然有互联网连接。重启 Docker 可以暂时解决。有人遇到过这种情况吗，或者知道该从哪里开始排查？

Been fighting with a weird issue on my home server: Docker containers run fine for a few hours, then networking inside the containers just dies while the host still has internet. Restarting Docker fixes it temporarily. Anyone seen this before or know where to start debugging?
