Did you check the other posts about the new ICMP check? You have to allow ICMP to external through your firewall

DocFraggle I tried Docker version 24.0 and disabled ipv6, enable_ipv6: false, which solved the error, but after adding the domain in the backend, checking the DNS reported an error 504, where do I check the cause?

Not only you need to allow ICMP outbound, but also for DNS to work properly port 53 UDP and TCP!
