Appium fails launching on iPhone Simulator, success on device

• Appium v1.15.1
• Mac 10.14.6
• Xcode 11.2.1
• Python test file.

I'm able to run the test on iPhone Device successfully, but on iPhone Simulator not.

Error:

[debug] [WD Proxy] Matched '/status' to command name 'getStatus'
[debug] [WD Proxy] Proxying [GET /status] to [GET http://localhost:8100/status] with no body
[HTTP] --> GET /status
[HTTP] {}
[debug] [HTTP] No route found. Setting content type to 'text/plain'
[HTTP] <-- GET /status 404 1 ms - 49
[HTTP] 
[WD Proxy] Got an unexpected response with status 404: The URL '/status' did not map to a valid resource

This is the Appium Server details:

Welcome to Appium v1.15.1
[Appium] Non-default server args:
[Appium]   address: 127.0.0.1
[Appium]   port: 8100
[Appium] Appium REST http interface listener started on 127.0.0.1:8100

Any suggestions?
