RDP Authentication problem with multiple WebSocket sessions on a single user

Hi,

I have a problem when getting AuthenticationInfo JSON from RDP GW with multiple Websocket sessions.

We are running our identical Reuters Client applications on 5 different machines. So we connect to RDP on 5 different machines (each of them opens a websocket) by using same client_id, user and password.

We login Refinitiv Data Platform (RDP) GW by using https://api.refinitiv.com:443/auth/oauth2/v1/token url.

So,

On startup, when we try to login GW with takeExclusiveSignOnControl=false value flag (we don’t want to sign-off others) and password method we cannot login.

So on next try we are setting its value to true (takeExclusiveSignOnControl=true) and can login to GW then.

0525-174619.339-I-(RdpGwAuthentication) - RDP AUTH: Authentication succeeded.

But when we also try to update the token (using previous token and sending to GW) we again encounter with the same problem. So we are again setting the takeExclusiveSignOnControl=true and getting a new token.

So on every refresh token step we get this error on all machines. This is the our case we want to solve.

With the above steps we have considered the below technical PDF information for the takeExclusiveSignOnControl flag.

We firstly send false flag to GW. But after we encounter error on login we send true flag value. So this invalidates refresh tokens on all machines!

As a note;

When we just run only 1 machine (so 1 WebSocket session) to connect RDP GW we have no problem for token updates:
