Restful switches stopped working since last update

The below configuration worked like charm for many months now, and stopped working since this morning update. I see “Entity not available: switch.garage_light” on the dashboard I’ve created and no switch exists on the automated lovelace. I’ve checked the endpoints and they are perfectly fine. Any ideas what changed?

switch garage_light:
  - platform: rest
    resource: http://192.168.36.26:12345/garage_light
    name: Garage light

switch tv:
  - platform: rest
    resource: http://192.168.36.26:12345/tv
    name: Tv

switch irrigation_lawn:
  - platform: rest
    resource: http://192.168.36.1:12345/lawn
    name: Irrigation lawn

Ok, I restarted HA core and everything is working fine as of now. I’m not sure what happened as I have not changed any configuration. I will come back here if it happens again.
