Usually it happens when server record missing in the database.
Try:
It will re-create all required tables.
Thanks for reply.I have done the same thing but it is showing Null pointer exception :
Could you please suggest alternative option to resolve this issue and i had to modify the db script because it was throwing error.

Most like a record in server table is missing. You can try to create it manually.

What is this script for?
This DB Script I ran on MYSQL server but it always thrown an NULLPointerException.
It working fine on default HSQLDB
Traccar automatically creates the database schema. Why did you run the script manually?
Thanks for reply.Script in traccar.xml is not working for mysql db.it thrown sql exception : CREATE TABLE "user".Invalid syntax etc.thats why had to run manually in mysql editor.
It does work if you use configuration from here:

Execute each query one by one. NB: Replace "read" & "write" in user_device table with some other name, later change those to default column names in phpmyadmin. Insert atleast one row in server table.
For Users table insert a row like this:
name : admin
email : admin
hashedPwd : ef38a22ac8e75f7f3a6212dbfe05273365333ef53e34c14c
