Why is it throwing and restarting RDP user from one PC (ip address)?

Question

RDP

Good evening, there is the following situation:
recently (March 2019) they installed a new server on win2012r2 (non-licensed hack.)
installed 1c + MSSQL and RemoteApp 1c
there, before that everything was spinning on a regular PC of wines 7 x64 (with a hacked RDP (patch rdp) used 1s).
the other day, RemoteApp 1c stopped connecting exactly on the PC (it is connected to a separate Internet satellite 1Mbit / s after a maximum of a minute it starts to issue a message). tried to log in through different users on this PC to no avail, on other computers connected via mobile Internet it enters without problems.
tried to follow all sorts of instructions, change the values ​​​​in security policies, it's useless, in particular: pyatilistnik.org/the-logon-timer-expired-on-the-rds
in general, the problem still remains (statics are registered there on the satellite, I think maybe it connects to the statics and remembers somewhere in the logs and writes everything down and then gives out such jokes ..... but where?
on other computers connected to the Internet everything works fine from different places ....
now I had to return to the old PC on win7 x64 (rdp connection), and that one connects to the 1s server locally

Answer 1

And from which openings of the world did you take the distribution kit?
There are 3 options here:
1) Distr is provided by ZverCd and other thrash makers.
2) The crack on Windows is extremely doubtful, other software too.
3) You messed up when setting up - by default, there is no such thing on the terminal server with the remote app.

Answer 2

What about client certificates? Checked?
