I noticed that this also happens when changing the networks. If I put the comüputer to sleep and then continue connected to other networks this happens. So either restart the computer or your docker. Seems to work for me. Had the issue 2 times already.
我注意到在更改网络时也会发生这种情况。如果我让计算机进入睡眠状态，然后继续连接到其他网络，就会发生这种情况。因此，要么重新启动计算机，要么重新启动 docker。似乎对我有用。已经有2次问题了。
