Unable to use fetch on iOS Simulator (Trying to access https://{domainName}.amazonaws.com:8080/{uri} ) (React Native)

I am building a mobile application in React Native which consumes my service (SSL Enabled) deployed to AWS. I'm unable to perform fetch on the AWS EC2 domain from the iOS Simulator. I can access the URL through Postman and simulator's browser. When I use fetch from the iOS Simulator, I'm getting a

TypeError: Network Request Failed

I have added the following to my info.plist.

<key>{domainName}.amazonaws.com</key>
            <dict>
                <key>NSTemporaryExceptionMinimumTLSVersion</key>

                <false/>
                <key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>
