When trying to do a remote debug connection from Windows to Linux it will time out and fail to connect. However, if the gdbserver is started first directly on the Linux machine and then connected to via Qt Creator then it works fine.
The error in the log is:
783target extended-remote tcp:10.239.32.78:10000
Failed to start application: Connecting to remote server failed:
tcp:10.239.32.78:10000: Impossibile stabilire la connessione. Rifiuto persistente del computer di destinazione.
Debugging has failed.
