This page isn’t working

lchhieu

I try to reinstall many times however still get the the error "This page isn’t working" when access to my domain.
I already point the domain to the IP of server + installed successfully
I used Ubuntu 24.04 LTS x64 and Debian 12 x64 and faced the same issue
(my server have ipv6)

I solved this issue by run

sudo ufw allow 80/tcp
sudo ufw reload
