cTrader 5.0.46 continuous reconnections

Using cTrader 5.0.46 for optimisation with dedicated machine Intel core i9 CPU 2,80 Ghz, RAM 32 GB, Windows 10

We see continuous reconnections that we do not see on other machines in the same LAN using other software.

Also, the optimisation in general appears slower than expected. 

Is this something that you have already flagged ?

Do you have suggestions ?

Thank you,

Patty
