Issue with running HSRP on two Nexus 9K in vPC?

[DalemonDalemon54256]

Hello, I'm having an issue with running HSRP on Cisco Nexus 9K in vPC. I've done the configs but when Initiate the "show hsrp" command on the Nexus 9Ks. its saying "Standby router is unknown" on primary switch and "Active router is unknown" on standby switch. Can anyone advise what's causing this issue and how to correct the configs ?

N9K-SW1# show hsrp
Ethernet1/11 - Group 2 (HSRP-V1) (IPv4)
Local state is Active, priority 110 (Cfged 110), may preempt
Forwarding threshold(for vPC), lower: 0 upper: 110
Preemption Delay (Seconds) Minimum:60

I've also included the running configs file

Thanks

HSRP VLAN must pass through the vPC link, i.e. VLAN must allow.

Hello

Whats the status of the interconnects between the two switches?
Are the N9Ks running vpc, Do you have a active port-channel between the switches?
Also make sure youve actually created the L2 vlans in the vlan database relating to the l3 SVI's

sh port-channel summary
sh int eth x/x status
sh vlan
sh vpc brief
sh vpc peer-keepalive
sh vpc consistency-parameters interface port-channel X
