Screenconnect Client can't connect to Host

If you found your Screenconnect Client can't connect to Host, just keep say "Waiting for retry", you should uninstall a ScreenConnect Client then install again.

Cause :
Client and Host connection is broken, for example my computer installed Screenconnect Client, my computer name will list on ScreenConnect Host, on the background between client and host with a ID, if the ID is broken, you can't fix it even reinstall the Screenconnect, so you should uninstall and install again to get a new ID.

Here is common case :

Case 1:
 - Client : uninstall the ScreenConnect.
 - Host : do nothing, host will never see the client online.
 - Action : If client install ScreenConnect again, what will happen, the Host will show two client, one is never online because client uninstalled.

Case 2:
 - Client : do nothing
 - Host : Remove the Client in Online status, Client side will uninstall ScreenConnect Client

Case 3:
 - Client : do nothing
 - Host : Remove the Client on Offline status, Client side may not uninstall ScreenConnect Client, then Client will keep always connect to Host but not successful, Host will not see the Client anymore.
 - Action : Client should uninstall ScreenConnect manually, if client not uninstall first, reinstall will retain the old connection ID, but the Host ID is removed, so the client will not success connect to host anymore and keep waiting for retry.
