jira couldn't able to connect to database

Pavan_04q8z0

Hello team

Jira is not able to connect to postgresql database.

firstly i have alter the password using below command:

Alter user jiradbuser with password ''; 
and then

I have used basic encryption method to encrypt the password , and copied the same password in dbconfig.xml

still the logs i can see 

database password decryption is not performed
password authentication for jiradbuser is failed

jira startup cheks failed
