ESPHome device suddenly unable to connect/connection timeout

Hi all. I tried searching through the community but couldn’t find an answer.

I have a few ESPhome devices that are connected to a separate IOT VLAN - 10.88.2.1/24

Suddenly, 1 of them cannot be connected via HA/ESPHome. I can see it on my unifi network connected and I can also ping it. The rest of my ESPHome devices remain connected and working.

Any idea how to fix this? I have tried putting in a manual ip in my parameters but to no avail. I have also restarted my network.

Thank you for your help!
