maximal possible terminals of MT5 running same time dropped from 18 to 16

 

the maximal possible number of terminals running simultainesly dropped from 18 to 16. this occors since installing latest april updates on my Windows server 2022. 

But since the MT5 terminals where getting updates as well i´m not sure which one causes the issue. MS or MQL5?


Anyone has the same problem? Solutions?
