Just installed and MOCA Lights off

I just installed the MOCA device, it ran for a while and then the MOCA lights dropped out and I lost the network connection completely. I was able to get them to restart by disconnecting and then reconnecting. My question is, when I look at the MOCA lights they are flashing, is that an indication the connection is unstable or is that normal for them to flash? I did the test of tying the two together and they linked ok.

Thank you!
