I was connected by team wiever from PC1 to PC2 but I had to turn off PC1, and when I turned it on I wanted to connect again with PC2 but I get "WRONG KEY" how can I reconnect? and started session on PC1 and PC2 but did not let me connect I already have the following option:
Submit Request - Denied
Request Confirmation-Denied
Password-Denied Connection

Is there any way to reconnect?
