problems with my mikrotik rb750gr3

Recently I buy a rb750gr3, at the start the device works fine when I enter to webfig, but suddenly not respond anymore, I got an error connection when I try from browser, I reset the device using the button but stills not works
the things what I test:

  • winbox: not works
  • change cable: not works
  • change port: not works
  • use another OS (win/macos) not works
  • change networks settings: not works

currently I can ping the device toi 192.168.88.1 , but still cant enter to webfig, please someone can help me giving me some ideas to configure the device?

thanks

use netinstall, and after that, do not use quickset and do not use random youtube videos.
