Clients of demo can't connect to master

[lyc-appert-44]

Hello,
I have trouble with demo mode, my master and clients are on the same LAN connected on the same switch. Veyon 4.2.1 64bits is installed on Windows 10 Pro 64bits, I've tried with and without firewall and antivirus.
Do i miss something?
Thanks

Hello @lyc-appert-44
what happens if you start the demo mode? Can you reach the demo server port (11400) on the master computer from a client computer while a demo is running? Do you have access control rules configured? If so, try to disable them temporarily on the master computer.

Hello,
You are right, the access control rules were the problem. Thanks!
