I fixed this issue be deleting all logshipping configuration on primary and secondary servers by below steps
On the primary server, execute sp_delete_log_shipping_primary_secondary to delete the information about the secondary database from the primary server. An example of the syntax for this is as follows:
@primary_database = N’AdventureWorks’,
@secondary_server = N’LogShippingServer’,
@secondary_database = N’LogShipAdventureWorks’
Execute sp_delete_log_shipping_primary_database to delete information about the log shipping configuration from the primary server. This will also remove the SQL Agent backup job:
On the secondary server, we then need to execute sp_delete_log_shipping_secondary_database to delete the secondary database, as follows:
after that recreate the logshipping configuration .
