Home Assistant Update and Internet Connection Issues

Currently running HA on a Windows machine, Core 6.0, version 12.3. No issues until swapping from an Amplifi Alien Router to a TP Link Deco XE75 Pro (5 APs). HA is on static IP. The PC is attached to one of the APs via ethernet. IP address not on the device list in the Deco App and HA is refusing to update. When I attempt to update, I get this message: Failed to call service update/install. Error updating Home Assistant Core ‘HomeAssistantCore.update’ blocked from execution, no host internet connection. Basically, can’t do anything that involves an internet connection. Any ideas? TIA
