screen shot of cert, thats what my main problem is , i followd every step and thats what i keep getting
SqlException (0x80131904): A network-related or instance-specific error occurred...
Named Pipes Provider, error: 40 - Could not open a connection to SQL Server
The network path was not found

This means my application cannot connect to SQL Server. In 99% of cases, this is a config / connection issue.
I check my connection string:
Server=...
I make sure it is correct:
If local:
Server=127.0.0.1
or
Server=.\SQLEXPRESS
If VPS:
Server=IP_ADDRESS

Most common mistake: wrong instance name (SQLEXPRESS vs MSSQLSERVER)
I open:
services.msc
Then check:
- SQL Server (MSSQLSERVER) or SQLEXPRESS

If it's not running, I start it.
I open:
SQL Server Configuration Manager
SQL Server Network Configuration
Protocols for MSSQLSERVER
Then:

Enable TCP/IP
After that:

Restart SQL Server
Especially if I'm using a VPS:
I open port:
In Windows Firewall:
Inbound Rules → New Rule → Port → 1433
In SSMS:
Server Properties → Connections
✔ Enable "Allow remote connections"
In Services:
- SQL Server Browser → Start
In the log I notice:
DbAdapter.cs line 50 / 266

That's where the connection string is set.
I double-check:
- Username / password correct
- Database name correct
- Connection string valid
I run this in CMD:
sqlcmd -S 127.0.0.1 -U sa -P password
If it doesn't connect, the issue is definitely on the SQL side.

My system cannot find SQL Server (network path not found)
I try this connection string:
Server=127.0.0.1;Database=DB_NAME;User Id=sa;Password=PASSWORD;
And I make sure:
- SQL Server is running
- TCP/IP is enabled
- Port 1433 is open
