Hi, Friends!

For the moment i connect with local Ip like 192.168… because i havent acces to my router settings, and i waitin my operator for Virtual Host settings.

My english is very bad, but i think is enoght. Sorry for that.

Please Help me

I didn’t get 100% but can you tell me if you set up cyberpanel on the local machine or if you set it on a remote server?

The server is work 100% perfect from outside. Sites work perfect from another devices… Server is 100% worldwide accesable.

But the machine internet is not working, i have “?” in ethernet icon on ubuntu.
When i try to install someting from terminal i cant access to internet.
When i try to open som website like google.com from firefox - i cant.

This is problem for me beacause. now i try to install SSL certificate to site and - i cant beacouse server cant install nothing becouse they not have internet.

this happens when i install Cyberpanel with 1 click
I try 6 times with fresh installed ubuntu and this problem was not resolved.

Maybe somethings blocked internet for security reasons???
