Hello everyone!

CONTEXT:

I created a new **CosmosReact Application,** using the Wizard, on an existing environment on which Pega Platform 8.7.3 is running.  
On this environment there are different Traditional UI applications.  
I created a new Operator with a dedicated Access Group, which refers the new Cosmos Application.

The application uses an Authentication service which defines a Basic Autenthication with Multi-factor authentication policy type.

PROBLEM:

When I try to launch the default portal (WebPortal) it does not execute.

It appears **Loading** but it never stops.  
Trying to understand the problem I investigated through the browser console and I have different HTLM error:

- Failed to load resource: the server responded with a status of 500 ()  
querying URL at  
/prweb/PrAuth/app/\<App\_Name\>/api/application/v2/portals/WebPortal.

- 401 Unauthenticated

Can anyone help me, please?

@RameshSangili thanks for your reply.  
After several trial and error and lots of tracer (browser dev console) I found the problem.

It was on the Service Packeg “Application” configuration, which contains the dx api v2 (used in my scenario).  
It was set a different authentication and this caused the error which I described. So, who is reading this solution: try to see the Service Package and understand how it works.

Thanks,  
Vincenzo
