Hi,

First of all, you need to check several things:
1. Is TCP / IP enabled in SQL Server Configuration?
2. Is Windows Firewall not blocking SQL Server port?
3. Are remote connections enabled in SQL Server Management?

Please refer to this post:
SQL Server Manager can not connect to a remote database[^]
