had seen by pure coincidence that the connection to the gateway did not work with ipv4 (in Foris)
All other points worked and the DNS and DNSSEC test also worked.
What could be the error here?
I had already restarted the modem
The console says so:
/$ check_connection Pinging 100.101.0.1 ... FAILED IPv4 Gateway: FAILED Pinging 184.108.40.206 ... OK Pinging 220.127.116.11 ... OK Pinging 18.104.22.168 ... OK Pinging 22.214.171.124...

And that’s the status in Luci:
