Centos-webpanel Installation Error - problems making Certificate Request

Dear members,
This is my first time in this forum and also first time using centos - webpanel.

I have a virtual machine in google compute engine and I have installed Centos - 7 on it. First time I succeeded with the installation and then I created a second virtual machine - with same configuration and tried to install Centos- webpanel. But this time the installation runs and it ends with this message :


===========================================

mv: cannot stat ‘clamd@scan.service’: No such file or directory
sed: can't read clamd-scan.service: No such file or directory

problems making Certificate Request
140178962253712:error:0D07A097:asn1 encoding routines:ASN1_mbstring_ncopy:string too long:a_mbstr.c:158:maxsize=64

============================================

But when I type my ip address on browser and goto it the default centos - webpanel page shows but I can't go to MY_IP_ADRESS:2030 which is admin panel. the page does not loads.

What should I do to resolve this?

ensure cwpsrv service is running.

routines:ASN1_mbstring_ncopy:string too long:a_mbstr.c:158:maxsize=64

Hostname is too long.  Hostname needs to be less than 64 characters

ensure cwpsrv service is running.

Cwpsrv won't run of there is no hostname certificate.  Seen the problem before.  Hostnames too long and can't make the cert.

Dear all,
Thanks for replying.
I'm running a vm on google cloud compute engine. I'm sorry this isn't relavant here but does anybody knows how to setup a host name in that?

Nano /etc/hostname
