Python nodes failing on parallel loop

Hi everyone,

I have a parallel loop that has multiple python nodes creating and writing to multiple excel files. It runs without a problem on a standard loop but keeps giving me errors on parallel loop below. I manage to get it to continue by continuing the run but quite unreliable. Can anyone advise?

Execute failed: The connection attempt timed out. Please consider increasing the socket timeout using the VM option ‘-Dknime.python.connecttimeout=’.

Also make sure that the communication between KNIME and Python is not blocked by a firewall and that your hosts configuration is correct.
