Smartthings Hub keeps losing connectivity

Ever since the update my smartthings hub keeps getting solid blue lights on the front of it and I can’t connect to it from my phone. It seems that it is actually connected though because I can see that it’s getting information from my devices on the developers web page for my hub.

I haven’t ever set up the ports in a specific way so I would assume all ports on my router are open. I have an AT&T modem and a TP-Link Modem.

If I unplug the network cable and let the blue lights start blinking the lights turn green again.

This morning I couldn’t use one of the main switches in my kitchen until I reset the hub. Very upsetting.

Any help would be useful.
