Fedora - Your partner did not confirm your query to view his/her screen - error

[antatj]

Hi ,
I have installed Timviewer on my PC with Fedora , turn off firewall, setup password, set acces control to 'confirm all' . Than, I have reboot Fedora PC to test whether the Timviewer service will be started on boot time. I have tried to connect Fedora from another Windows PC and everything works fine.
But now, when i try to connect i have got a message
"Your partner did not confirm your query to view his/her screen"
What's happens ?
Thanks
