[Samba] Migrating to Samba 4.9.4 AD, kinit administrator -> kinit: Cannot contact any KDC for realm...

Hi there

I have migrated from an older version of Samba DC to Samba 4.9.4 AD.
Running Centos 7. One server with everything on...  (AD and file server)
Bind 9.9.4

Built from source.
Followed directions in the wiki.
All seems to go fine, but when I startup samba-ad-dc it shows a few errors.
    ([kdc failed to setup interfaces])
The initial tests (in the directions in wiki) go fine until I get to  
"kinit administrator" and it
just gives ->   kinit: Cannot contact any KDC for realm 
'BHUBFAB.DDNS.NET' while getting initial credentials

...has been 3 days now, eish.

Smb.conf:

# Global parameters
[global]
         bind interfaces only = Yes
         interfaces = lo enp0s25
         netbios name = SIMBA
         realm = BHUBFAB.DDNS.NET

         server services = s3fs, rpc, nbt, wrepl, ldap, cldap, kdc, 
drepl, winbindd, ntp_signd, kcc, dnsupdate

Did you by any chance upgrade from Samba version 4.7.x (or earlier)
directly to 4.9.4 ?
If you did, start downgrading again, it doesn't work, you will have to
upgrade to to a 4.8.x version first.

Thank you for quick reply!
Unfortunately I did not make a note of the previous version, but I think 
it was 4.8.3

I will try install 4.8.x from source, run the classicupgrade, and see if 
it works.

Many Thanx
