VS Code unable to connect BC Instance


The VS Code on my VDI can not connect to the Business Central Instance ( on Server B ) due to below error message. The VS Code and BC Instance are installed in two different machine.


I can access BC environment using Web Client on MY VDI but can not connect BC Instance and download the symbols.

Configuration of BC Instance

1. Business Central 20.8
2. Development 7049 (Opened in firewall)
3. Enable Developer Server Endpoint (checked)

Kindly help me to solve this issue.
