Hello @navylos_ear you had some answers and help here, but they were misguided and missing the root cause of the problem. So I have deleted those posts to clear the confusion.
To be clear, you are having issues communicating with the raspberry pi over the network (cannot access http://192.168.2.2:2770 through the browser), so now you have connected a keyboard and a monitor to the Pi to troubleshoot. The messages that you see on the monitor are from the boot process, and they are all normal, and not the cause of the network problem (even the lines that say error and exception, the pixhawk autopilot connection is ok and it should still work).
What you need to do is verify your network configuration and communication. Your computer network is not configured correctly to connect to the raspberry pi.
Please carefully follow these troubleshooting steps here, which should solve your situation. If you have a problem with these steps, let us know.
