ISIS Authentication Issue

Hello Experts,

  So I am very frustrated right now as I have searched around online and gone
through a couple of Cisco guides and my configs look right as shown below

R2
router isis
 net 52.0001.0000.0000.0002.00
 is-type level-1
 authentication mode md5 level-1
 authentication key-chain cisco level-1
 metric-style wide
 set-attached-bit route-map D
 mpls traffic-eng router-id Loopback0
 mpls traffic-eng level-1
R7
router isis
 net 52.0001.0000.0000.0007.00
 is-type level-1
 authentication mode md5 level-1
 authentication key-chain cisco level-1
 metric-style wide
 set-attached-bit route-map D
 mpls traffic-eng router-id Loopback0
 mpls traffic-eng level-1
R8
router isis
 net 52.0001.0000.0000.0008.00
 is-type level-1
 authentication mode md5 level-1
 authentication key-chain cisco level-1
 metric-style wide
 mpls traffic-eng router-id Loopback0
 mpls traffic-eng level-1
R9
router isis
 net 52.0001.0000.0000.0009.00
 is-type level-1
 authentication mode md5 level-1
 authentication key-chain cisco level-1
 metric-style wide
 mpls traffic-eng router-id Loopback0
 mpls traffic-eng level-1

but I keep getting the following erros on all of the routers;

00:23:23: %CLNS-4-AUTH_FAIL: ISIS: LSP authentication failed
00:23:54: %CLNS-4-AUTH_FAIL: ISIS: CSNP authentication failed

I have already rebooted the routers, but it starts with the same errors
again.

Regards,

James
