On server 2 I have two sensor (sensor.test1 and sensor.test2 with value unknow)

On server1 I have this notify :
Login attempt failed
Login attempt or request with invalid authentication from 10.0.0.70

When I restart server 1 value of sensor in server 2 change from “unknow” to “unavailable”

Some one can help me ?

I went down this path a few years ago, there is event stream and statestream. To be frank I run around 3 instances plus a few stand alone at my place and the best tool for syncing data across them is Node-Red.

I think you need something like this, where LLAT, where LLAT is your Long lived Access Token

- platform: rest
    resource: http://10.0.0.72:8123/api/states/sensor.couloir_temp
    name: test1
    value_template: '{{ value_json.state }}'
    unit_of_measurement: "°C"
   headers:
      Authorization: 'Bearer LLAT'
      Content-Type: application/json

You can connect multiple ha to one node-red instance. From there it’s up to you how you wish to get the data I use mqtt but there are many options to do it.
