ERROR: Sending settings to client faile

This is for Internet clients? do i need to open additional ports on the windows clients to get this working? or is it something else?

I opened the below ports on my router and this problem still persisted however when i disable the windows firewall the error stops happening is the installer missing opening a/some ports on the windows firewall? If so exactly which ports should be open on router and windows client? I am a bit confused after reading the Admin Manual several times, and have enabled the following ports on my client router and will do the same on my windows client firewall however some confirmation of this would be greatly appreciated :D as i do not want to open to many ports or leave windows firewall off
