yum update error

[sn]

I installed a new cloudlinux 5.6 server and registered using rhnreg_ks.
I see the server in CLN, but get this error trying to run yum.

[root@xxxx ~]# yum update
Loaded plugins: fastestmirror, rhnplugin
Loading mirror speeds from cached hostfile

[iseletsk]

please, try doing:
yum clean all
and see if that helps.

If it doesn help -- could you contact our support, preferably with access to the server.

Today it works without any interactions.

I ran yum clean all yesterday and got a little further but ended out with the same error.
Today i ran the same commands and it just works.
