QUESTION AND ANSWER
Repeatedly Disconnected From Host After Connecting
An ISP at either the host or client (or in between) is not delivering a stable connection due to packet loss and/or very low connection speeds. Contact the ISP to advise once it's been determined that this is the issue.
When connecting to your host computer, two calls are made - the first is to the GoToMyPC server to verify the account and create the connection (both client and host connected to GoToMyPC here). The connection is then made from client to host (GoToMyPC servers are no longer involved).
