Issue with Ikev2 ipsec vpn initiator waiting for auth response

[NetworkerC]

I am currently facing an issue with one of my ikev2 vpns. The issue is that some remote ips that are on the vpn are unreachable (these were working earlier) and giving send errors on phase 2 output when i try sending any traffic. On the phase 1 it shows its on status: in-neg and says initiator waiting for auth response. What could be the issue and how can it be solved?

Hello @NetworkerC 

If phase 1 is stuck on "initiator waiting for auth response," it sould be an issue with authentication.

--This could be due to incorrect credentials, certificates, or pre-shared keys...

I run lab last week and believe me it take two long weekend days to solve issue same as this 
please share the crypto ikev2 profile and keyring (hide the password) <<- both peer please
