If Windows Defender Firewall or any antivirus tool is turned on, make sure to configure them to allow the database server port (2638 in this tutorial or the port number you choose to use) to go through, otherwise, connection errors may occur.
You would need to configure the firewall/antivirus settings on the following servers:
-
Database server -- to allow the database server port (2638 in this tutorial)
-
.NET server -- to allow the .NET server port (5009 in this tutorial)
-
Web server -- to allow the FTP server port (21 in this tutorial) (this only affects the FTP connection during the app deployment)
The following steps configure the firewall settings on the database server (you can take the same steps to configure the other servers):
Step 1: Open Windows Defender Firewall and then click Advanced settings.
Step 2: Select Inbound Rules and then click New Rule.
Step 3: Create a new rule which allows connections through the database server port (2638 in this tutorial).
