I want to login my panel, but i get this message. and it just loading when i want to login panel

Hello, is the problem solved? Is it normal to try restarting the panel? Also check if the server can connect to our node server?

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

Permanent
vim /etc/sysctl.conf

net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6=1

For the settings to take effect use:

sudo sysctl -p
