What information does not work prompt? It is recommended to turn off the ipv6 of the server first and then check the address of the panel
Temporarily close ipv6 and execute the command:
sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1
sudo sysctl -w net.ipv6.conf.default.disable_ipv6=1
sudo sysctl -w net.ipv6.conf.lo.disable_ipv6=1
