Installing Laravel with a database on another system

We have a local network, in the server's system I install SQL Server 2017, now I must install Laravel in my system with the server's database but I got this error

Connection failed: SQLSTATE[08001]: [Microsoft][ODBC Driver 13 for SQL Server]SQL Server Network Interfaces: Connection string is not valid [87].

my config
