Gray Screen

[Andrea Pessina]

I have installed Veyon server on PC with Windows 11 in a windows Domain. The domain user is a local administrator of the PC.
then i have installed a client with wind 11 in the same domain but the user is not a local administrator.
both in LDAP or via keys the client is in gray screen and all commands doesn't working

Grey screen usualy mean that computers do not communicate, if you use LDAP does the "integration test" work well? If you use "locations & computers", do you enter IP or machine name? If you use machine name can you ping the client with his name from the Master?
You may have firewall on PC or access lists in switchs that can block TCP ports?

@Andrea-Pessina - You most likely need to allow TCP port 11100 inbound/outbound on both the master and client servers. That helped me at least.
