OpenEPaperLink HA integration- index.html not found

My AP stopped working and I don’t know why.
When restarting the AP, I get the IP address and the green “connected”.
But, when I go to the IP address for the AP, I get “index.html not found. Did you forget to upload the littlefs partition?”

I bought the AP and five tags about a year ago. The firmware was already flashed to the IP and tags.

Do I need to reflash the AP, and where can I find the binary or YAML for the AP?

Do you have DHCP?
Did the AP get a new IP?

The IP didn’t change, plus it shows on the AP screen.
