Just the day after getting everything fine: net::ERR_SSL_PROTOCOL_ERROR , during installation of another software in the PC I got problems with grub system in Ubuntu 18.04.4 Desktop, which I resolved copying, from an installation iso image, the /bin/bash folder: https://askubuntu.com/questions/1210267/missing-operating-system-error-unknown-filesystem-grub-rescue
But to my surprise, now I’m not able to see my webpage anymore, even if, apparently, everything seems ok.
"
This site can’t be reached https://ggc.world/ is unreachable.
ERR_ADDRESS_UNREACHABLE " :

What aspects, elements, configurations, do I have to check and verify?

Looking forward to your kind help.
