Error conecting to server
on: May 26th, 2022, 12:28pm 		Quote Quote  Modify Modify
Hello, I have the client app in a server with windows 2019, It cant connect to another windows 2019 with the server app.
 
The server app is connected to another clients without problems. I have license not used, isn't a license problem.
 
If I begin a callback connection to the client app, It works correctly.
 
But the problem is, the callback connection isn't restored when the server restart with automatic updates.
 
I need a full automated solution.
 
Thanks.
 
The debug log:

Hi,
 
Thanks for using our product.
There is no option to restore the call back connection because there is no such connection in the server GUI after the PC reboot.
I mean USB over Network doesn't have such feature. But we'll implement it in one of the next releases.
Use USB over Network (server) CLI to create a callback connection for automation:

callback add <host> [<port>] [-m <message>] [-p <password>]

Thanks for the reply. The workaround is good, but what about the initial issue?

Hi,
 
1) Initial issue is "the callback connection isn't restored when the server restart".
2) "Can`t connect, network subsystem error" is another problem. I have sent you an email. Please reply.
