Tried setting up remote desktop view into a CentOS7 server following the article here. But when trying to sign into the remote dekstop from Windows Remote Desktop Manager, getting disconnected after entering credentials. Ie. this is as far as I can get:
Looking at the ~/.xsession-errors
(just from following a post here) for the user, seeing...
[testuser001@HW006 ~]$ cat .xsession-errors
Failed to open connection to "session" message bus: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.
Running without a11y support!
Error: cannot open display: :12.0
Checking some basic stuff, nothing seems amiss to me

Not really experienced with networking stuff, so not totally sure how to proceed / debug from here. Anyone know what could be causing this and how to fix / debug?
Workaround solution: uninstalled GNOME desktop (have had several other RDP problems with it in the past), installed MATE, and used the article here https://www.hiroom2.com/2017/10/01/centos-7-xrdp-mate-en/
