Https ToxiProxy & Postman

Hi All,

I have an upstream https service, in which I would like to inject delay using toxiproxy.
Postman ( https://x.y.com:5556/a/b/c + request ) <-> Response (works)
Postman ( https://localhost:10200/ + request ) <-> ToxiProxy ( refer below ) <-> No Response

I am on macOS,
Below are the settings I have tried.

Start the server ./toxiproxy-server

1. Toxiproxy-cli create https-https --Listen localhost:10200 --upstream https://x.y.com:5556/a/b/c
   or
2. Toxiproxy-cli create https-https --Listen localhost:10200 --upstream https://x.y.com/a/b/c:5556

With 1st
INFO[0179] Accepted client client=127.0.0.1:49200 name https-https proxy=127.0.0.1:10200 upstream:https://x.y.com:5556/a/b/c
ERRO[0179] Unable to open connection to upstream client=127.0.0.1:49200 name https-https proxy=127.0.0.1:10200 upstream:https://x.y.com:5556/a/b/c

Today, I am using postman as client, I would like to expand to Jmeter, Java HttpURLConnection.
Can someone please guide, point to any tutorials etc.

Thanks and gratitude in advance.

Start by reproducing the HTTPS proxy setup from the issue with toxiproxy-server and the two toxiproxy-cli create commands on macOS. Compare the direct Postman request with the localhost:10200 request and inspect the logged upstream connection failure; done means a request receives a response through ToxiProxy.
