z4k-zkm password authentication failed

When run command “helm install z4k zerto-z4k -f values.yaml -n zerto”,

z4k-zkm pod occured ‘password authentication failed for user “postgres”‘ error

(I saw through this command ‘kubectl logs z4k-zkm -n zerto’)

I cannot understand why this error is occured

Please tell me the solution that how can solve the problem

Thank you
