OSPF peering not forming when authentication is enabled

Question

OSPF peering between two of my routers went down 2 days before. After troubleshooting, I removed the authentication commands from both devices GRE tunnel interfaces

ip ospf authentication message-digest 
 ip ospf message-digest-key 1 md5 xxxx

Then the peering formed. So OSPF peering is not forming when authentication is enabled but forming when there is no authentication.

Please note that password is same and there is nothing wrong with authentication configuration.

I'd like to make OSPF work with authentication enabled.

Please find the config below:

interface Tunnel10
 ip address 192.168.10.13 255.255.255.252

 no ip unreachables

 ip ospf authentication message-digest
 ip ospf message-digest-key 1 md5 7 645454654
 keepalive 10 5
 tunnel source 10.10.1.10
 tunnel destination 10.10.1.26
end
