Error: 18456, Severity: 14, State: 8 XP_Readerrorlog JDBC

Hi Experts,

I am using SQL Server 2008 and fromt end application is in Java. Very recently after the maintance activity (Restrated Server) am facing the below issue in the xp_readerrorlog "Error: 18456, Severity: 14, State: 8 Password mismatch....from the client [Ip Address]".

Database connection have been made through "JDBC". We checked the password in the connection string of JDBC as well in the sql login both are same.

Can any one help me how to fix this.

Many thanks in advance.
