Sign in again in the app on this computer to connect to other PCs. This can appear after a long period without outgoing connections when the app becomes host-only. It is separate from permission for incoming connections.
The host is the remote PC; the client is the PC you connect from. If you cannot locate logs, start by sending the error code and detailed reason from the error window.
The error code alone does not show whether a device failed or a firewall blocked the connection. Check the detailed reason and logs as well.
