Error while connecting RDP "an authentication error has occurred the token supplied to the function is invalid".

an authentication error has occurred the token supplied to the function is invalid

I have installed xrdp 0.9.8 at server side.

Remote desktop connections are working fine when i am connect it from windows 8/10.

but when i am trying to connect RDP from windows 7 it is showing error which is showing on left side.








in xrdp 0.9.8 TLSv1.2 and TLSv1.3 is added by default.
in older version of windows system TLSv1.3 was not supported. thats why it is not connecting with xrdp server.

To resolve this issue from server side follow the steps below.
1. Login to xrdp server.
2. navigate to xrdp configuration file location,

$cd /etc/xrdp
$vim xrdp.ini

replace
ssl_protocols=TLSv1.2, TLSv1.3
with
ssl_protocols=TLSv1, TLSv1.1

3. Restart xrdp service.
$ service xrdp restart

  3. A user can easily conduct a set up of the Epson Printer Driver for that the user should press the start button in the left corner of the screen further the user will get to see a popup menu appearing further the user should type “update” in the search bar. Further, the user should check the availability of the updates and should get the updates installed if needed.
