Hello everyone, I have a problem when I get this error and then says that the port can not be opened
There’s a problem with your code. Without seeing your code (ideally, posted here in plain text format inside a preformatted block) we can’t help.

I will do it the next time I got this error because we are in tests, the thing is that there is an script in background and stays there but we don’t know why

In your funcionesAutoSeguroLineas script library, are you calling system.util.invokeAsynchronous somewhere? Seems like you are and it’s happening within that call.
Post your funcionesAutoSeguroLineas script
I think this is relevant.
