I run a VPS server. CentOs 9 stream.

When I try to do anything with DNF or YUM commands, it always returns, ‘Killed’.

For example, When I try run, ‘dnf update’
it returns,

[root@centos-s-1vcpu-512mb-10gb-sfo3-01]# dnf update
Killed
[root@centos-s-1vcpu-512mb-10gb-sfo3-01]#

When I try to run, ‘dnf install unzip’
it returns,

[root@centos-s-1vcpu-512mb-10gb-sfo3-01]# dnf install unzip
Killed
[root@centos-s-1vcpu-512mb-10gb-sfo3-01]#

I tried running, ‘dnf clean all’ command. But it did not fix the error.
