Hass.io rpi2 unplugged and replugged and now won't log onto network

So I my rpi2/hass.io was working fine but I had to unplug it and move it to another power socket. So it’s lit up and stuff but I don’t see it on the network. Ive rebooted my router but nothing. What do I do now?

can you connect a monitor and keyboard to it to get into it that way?

maybe try rebooting the pi also if you haven’t done that.
