Deploy Outlook Add-in on an AWS EC2 instance

Question

We are trying to host a custom Outlook Add-in on an AWS EC2 instance. We are using a windows server in EC2 to host this. Currently we are using webpack dev server to host it locally and everything is working fine. Now we need to deploy and have this app run as a service in the Windows Server.

We have tried to deploy the build on an IIS server. But we were not able to proceed after logging in to the application. We are getting the error as a Bad request. We also have tried to deploy it on Apache server using XAMP. But the results were the same. It is getting deployed in the webservers, however when we are hitting the backend application it seems to be erroring out.
The error we are getting is Error: redirect_uri_mismatch, when we try to authenticate and redirect to the authenticated home page of the application.

When we deploy the same using webpack-dev-server in the instance, It is working as indented.

We are facing issue to identify the proper reason for this error and unable to deploy the service in EC2.
