I have a network manager icon with exclamation mark how to debug what caused this exclamation to appear? what logs to check, maybe wireshark would help?


Connectivity-check determines that you have no global connectivity. What gives nmcli general connectivity?

Of course you could just ignore the icon or disable connectivity checking (see `man NetworkManager.conf``). But it would be interesting why NetworkManager thinks that the internet is unreachable and fix the underlying issue instead. Enable level=TRACE logging and look at syslog/journals.
