Clean installation R80.10 and error "The connection with the server was lost. Any unsaved changes are preserved "

[Dmitriy_Chazov]

Good day to all.
I started to test the solution CheckPoint R80.10 take 462. Faced an incomprehensible situation for me. After applying the policy, I get the error "The connection with the server was lost. Any unsaved changes are preserved ", after which I can not connect using both SmartConsole and SSH and WebGUI.

What I'm doing.
I spread out CP R80.10 as a virtual machine on Hyper-V
Scouting option - standalone
I update OS - I put R80.10 jumbo Hotfix Accumulator (Take 91)
I define the topology
I attach the license and import contracts through UserCenter
I create an initial rule in Access Control for access from my working host to the gateway
Apply - Install Policy
...
I get the error The connection with the server was lost. Any unsaved changes are preserved and fall off

Tell me what's wrong and watch?

P.S.

+ In addition, I repeated the procedure several times but without updating the R80.10 jumbo Hotfix Accumulator (Take 91) and got the same problem(

UPD1:

When you type the following command

$MDS_FWDIR/scripts/server_status.sh

We get the following information

Server is up - but not ready to receive connections (fwm might be down or busy)
