Hi Sagar,

As if suggetsed by Mark above, please change the below parameters in NWA;

ume.r3.connection.master.poolmaxsize

ume.r3.connection.master.poolmaxwait

By changing these parameters, you may not get the HTTP 401 error.

Hope this helps.

Hi Sagar,

Please check this blog under section 2.2.2 HTTP 401 - Authentication Failure

Potential cause for the error: 
Calling the AF may result in HTTP 401 during high load; this is caused by too few connections to the 
ABAP user management or a timeout waiting for a new connection. 
In the standard J2EE installation the User Management Engine (UME) is configured to use the user 
database from ABAP-backend. 
UME has a connection pool wrapper which takes connections from the JCo pool for the backend 
communication. During creation of a session within the J2EE engine this user is verified directly in the 
ABAP-database. 
The connection pool for these verification calls to the ABAP-side is controlled with J2EE properties in 
the J2EE service 'UME Provider‘. The problem here is that this connection pool gets exhausted - its 
default for max number of 10 connections gets reached, and there are no more connections for the 
other application threads. 

The solution is already provided on the document.

Hope this helps,

Hi Sagar,

        Please check whether the user being used is assigned one of the following roles SAP_XI_IS_SERV_USER, SAP_XI_APPL_SERV_USER,

SAP_XI_DEVELOPER_J2EE, SAP_XI_ADMINISTRATOR_J2EE. Assigning any one of these roles to the user provides necessary permissions for the user to access.
