Hi Antonio,
You mentioned earlier that you are running wsp_deploy.bat. Please try with running wsp.bat instead.
Also, make sure that you have edited the wsp.xml in the <DefaultCluster> section to use 9786 for the <port> setting (since you are using the ESP Studio to run the project, and that uses port 9786), and <SslEnabled> needs to be set to false (since your project is running in "esp://<server>:<port>" and not "esps://<server>:<port>").
Thanks,
Alice
