Do not enter the panel

I think it’s a good panel option, I installed the panel in a minimal 7 centos, everything was installed correctly, but when entering the administration panel gives us the following error.

This site can not be accessed
It took too long to respond. .

I contacted server support and gave us this answer

It appears that your container is setup with a custom software which caused the container to be missing many system components, I advise you in this case to backup your data in Recovery mode and Restore the server cleanly or you can try to resolve this issue in Recovery mode, to view your files and filesystem you will need to type the command chroot /mnt.

Kindly provide these details:

Provider: server4you
