for details refer
https://docs.mulesoft.com/api-manager/v/1.x/accessing-your-api-behind-a-firewall
For testing purpose as quick fix "Bypass the proxy". Select option next to "Mock Service" stating " API is behind a firewall"
Actual fix before you implement it in Test/Production environment is to implement and apply a CORS Policy for your browser to be able to load the resources in the API behind your firewall and the Anypoint Platform’s browser tools

Mechanical Sympathy - Learning from Racing
Formula 1 world champion once stated
“You don’t have to be an engineer to be a racing driver, but you do have to have Mechanical Sympathy.”
– Jackie Stewart, racing driver
This fits so well with technology. What Jackie meant is that understanding how a car works make you a better driver. This is so much true for writing code mainly in today's cloud technology. You need to have a basic understanding of hardware to create a good software.

Unable to connect - Azure Hybrid Connections
After you have configured the Azure App Service Hybrid connection, you might have a scenario when the Status of showing up as "Not Connected"
Azure Portal - > App Service -> Select App - > Networking - >Configure Hybrid connections
"Status : Not Connected"

One way to get more information on the issue is to run a get-hybridconnection powershell command in On-Prem client machine
In this case server was not connected to the internet. The server was placed in private subnet with no NAT gateway connectivity to internet. Once the server was connected to internet , issue was resolved.
