Hello all,
i have 2 Vserver with centos 7 and Cyberpanel, everthing was fine 
2 days ago I noticed that when logging in via shell, it takes me a long time until the password is asked for, about 30 seconds.
Then I noticed that only the IP is displayed in the login instead of the name.
A ping on google.com or another domain is not possible, a yum update is also not possible time out. iptables were not changed, nothing was done. I can’t read my Cyberpanel version https://IP:8090/base/versionManagment ServerError 500 either.
wget or curl is not possible, i have a Problem with the Name Resolving?
yum update
Loading mirror speeds from cached hostfile
Could not get metalink https://mirrors.fedoraproject.org/metalink?repo=epel-7&ar ch=x86_64&infra=stock&content=centos error was

or
ping 62.141.42.*
PING 62.141.42.* (62.141.42.*) 56(84) bytes of data.

what can i do? i think is a Network Problem on the Master Host from my Hoster?
thanks in advance for any idea
