Hello!
Or that any "Network Lock" mode is disabled by setting "Network Lock" box to "None" in "Preferences" > "Network Lock" window (default: "Automatic"), as it is indeed the case according to the system report (important option not at default: netlock.connection false) and considering that the user's system does have nft and iptables-* installed. Splitting the different cases with different messages and logging them will be suggested to devs.
Kind regards
