After Ubuntu installs xrdp, windows can connect to the server remotely, but cannot log in and report an error problem connecting

A novice to linux, I don"t quite understand what the problem is. I bought a $2 vps, from cloudcone to put it on a blog, and then I installed a graphical interface xrdp, on the widnows remote Desktop according to the installation on the Internet. However, I tried N times in the login interface, but I really couldn"t log in, but I could log in with a username and password on the Xshell client. If I don"t know why, ask the boss for advice on


.

when I get here, there will be a problem with the connection, and I am confused. I can install the connection normally using the user name and password sent to the mailbox when I buy it. (just don"t pull it to the wall, thank you)
