SMT is configured on SLES 12 SP 3.
SMT Client(SLES 12 SP 3) is also configured via "clientSetup4SMT.sh" script. I updated/patched the smt client systems too.

But on SMT Server when I run the 'smt-client' command it show 'Patch Status' as UNKNOWN

smt:~ # smt-client
Code:
.------------------------------------------------------------------------------------.
| GUID                                 | Hostname | Patch Status | Patch Status Date |
+--------------------------------------+----------+--------------+-------------------+
| SCC_6524b7f12a39410e8588b60170e681e1 | node1    | Unknown      |                   |

'--------------------------------------+----------+--------------+-------------------'
while 'smt-list-registration' gives the appropriate output:
smt:~ # smt-list-registrations
Code:
.----------------------------------------------------------------------------------------------------------.

please help why 'smt-client' is showing the Patch Status as UNKNOWN ?
