Hello Jonathan,
Just wanted to clarify a few terms. The connection name is actually just a descriptive name for the entry in the address book. Whereas the actual value used as a remote computer address (this can be a hostname/DNS, an IP address or
Internet-ID) is stored in either the "Direct connection" or "Internet-ID connection" field. I assume that it is one of these fields that you mean when you mention the connection name.
but is there anyway to prompt the host to check the device name and update its entry in the address book.
This problem does not exist if Internet-ID connection is used because the Internet-ID code stays the same on the host regardless of computer name. If you explicitly use
direct connection though, there is no way for the Host to communicate back to the Viewer in case its hostname has changed. The Viewer will simply show the Host as offline in its address book.
You can try the following solution - switch to using Internet-ID connection. While this connection type uses an intermediary server the program still tries to find and use direct route between Viewer and Host, if possible. For this to work you should still keep the incoming TCP port 5650 on the Host open though, just as with the regular direct connection.
If you don't want the program to connect to our public ID servers feel free to install and use the
self-hosted server, it's free.
Hope that helps.
