I found the problem, On maya 2014 the warning is considered a "real warning" except special case or it is a "warning error". On maya 2018 the warning that I print to be considered as an error and therefore my try / except captures the error and sends it back to me ...
In fact the error of the socket module 10061 is normal ... So my code with error is: try: sock.connect((s_host, i_port)) b_connected = True except Exception, e: cmds.warning(e) b_connected = False And solution is: try: sock.connect((s_host, i_port)) b_connected = True except Exception, e: qd_logger.debug(e) # Python logging module b_connected = False -- You received this message because you are subscribed to the Google Groups "Python Programming for Autodesk Maya" group.
