The wi-fi connection is available but apps can't connect to the internet

hello, I am a new endless os user (and I didn’t use linux before) and I have a problem. I have connected to the internet and I can use google chrome or chromium without any problems, but if I open an app e.g. discord, it tries to update self but fails
