How to solve internet connection problem on chrombook?

Question

Chromium

Good time of the day! Due to my natural narrow-mindedness and limitations, I can’t solve the problem of connecting a chrombook to the control unit of the device (not the essence of what), I immediately apologize for my complete lack of knowledge of terminology, but still I hope for understanding and assistance. Chromebook with a wired connection (lan) sees the device, but when you enter the corresponding ip in the address bar of the browser, it gives a connection error "err address unrechable" error code 137. Ip , input mask and gateway are entered correctly, server name automatically. Searching for the corresponding error on sites dedicated to chromium os did not lead to a solution to the problem.
