Thank you for your patiance & your question,
The bot 'Service Account' provided for your bot application on the Symphoyn Develop2 pod environment would consist of a RSA Key pair (Private & Public). The public RSA key would be required to be uploaded via the Symphony Admin Portal and applied to the specific 'Service Account' used for the bot application.
With the error message you have provided - it looks as if there is an error with the authentication where it is not allowed to proceed any further. This could be due to the RSA key not being assigned to the 'Service Account' on the customer's pod environment. Only the Administrator of the customer pod environment can upload the Public RSA key to the 'Service Account' before the bot would be able to autheticate.
Please check with the administrator if the bot has a dedicated 'Service Account' & if you need to either provide the RSA key pair or generate a new set of RSA key pair to work on the customer's environment.
If you have any comments or feedback please let us know.
