Rak7249-not able to connect to AWS lorawan server

Hi,

Rak7249 with firmware V1.1.0064_Release_r208 is not able to connect to the AWS lorawan network server. I get the following error message in logs - user.err basicstation[17344]: [AIO:ERRO] cups contains malformed auth token - expecting: {header: value\r\n}*. Has anyone able to get this working?
