Cant connect to dude "Connection Closed" from specific IP

Hi Guy’s,

I have an issue while connecting to dude server from my laptop.
From another PC i can connect just fine.

From what i checked the “Panel” section is fulled with connections from my IP address.

Does the dude/mikrotik has a maximum connection value?
How can i disconnect the existing panels?
Reboots to the routerOS didnt help in this case.

Regards,
Guy.
