I read about attacks on the network before, but until now I hadn't been affected.
That changed now and from the logs, this is what happened:
Within a relatively short amount of time I lost all my peers and my wallet is unable to reconnect to the network.
I'm not sure if that's the same problem other people are facing.
I think you are banned for a period of 24 hours, because the algo finds you're misbehaving.
You can try to connect from a computer with another ip to check.
This happens to me once in a while.
I think the exact opposite is the case. It disconnects other nodes right after I received a block. However, the result is the same: I'm disconnected.
In the meantime I'm once again connected without changing anything and all is running fine.
