Weird Networking Issues After power outage

Hey All, I have a power outage and on restart, I've had some weird network issues since restarting.

When I restart and remove I mount the array, I have full network on unraid, I can ping google etc. When I mount the array (which starts all my docker containers) I have a connection for about 10 seconds and then it dies, I can still access the web Ui but unraid can't reach Google and all my docker containers show they are up but the web UI and stuff are unreachable and the logs show it is timing out as the try reach external things.

 

Pinging during the array start, the 400ms change 
```

I have DHCP starting at 100 and have a static IP set on the unraid machine below DHCP. Im honestly kinda stumped at what might be causing things.

This suggest a container continually trying to restart.    You should be able to work out which one by looking at the uptime on the docker tab.
