VNC "Connection Closed"

[RealG187]

When I was on VNC for no reason it said connection closed, It kept on doing this, I used RDC and it worked and shortly after VNC worked, but did it again, I am sick of it saying connection closed, I dont even know WTF that means, and that is not a good message cuz it doesnt even give any info whatsoever about why its not going.

Now it says my connection has been rejected
