Authorization URI not landing while selecting the devices from "My Testing Device"

I have set up a project in the Developer workspace, settings are as follows.

SmartThings Cloud Connector
Hosting = AWS Lambda

The project has been set up successfully.

Authorization URI does not land while selecting the devices from “My Testing Device”, although I can view the Authorization URL if I use it outside the SmartThings App.

My Authorization URL is an App Client created inside AWS Cognito, when I client on my device inside SmartThings App it gives me the following error.

Couldn’t add a device

A network or server error occurred. Try again later

Please refer to where I’m mistaking it as the Authorization URL seems to be working fine outside the echo system of the SmartThings App.

Hi, @vahaj.

So, this means that, when you go to “My testing devices” and tap on your ST Schema Connector, you immediately get the “network connection” error?

So, you’re using AWS Cognito in this section, correct?

In the App Client, are you receiving a GET request?

@nayelyz, yes when I go to “My testing devices” and tap on your ST Schema Connector, I immediately get the “network connection” error.

Yes, I’m using AWS Cognito.

Yes, the GET request is working fine, when I’m using the URL separately defined in the Authorization URL, it’s working fine.
