Well, this looks like a networking issue. Can you ping that IP address?

BrunoGiubilei commented 5 years ago

@gotthardp yes

can i debug the script?

gotthardp commented 5 years ago

Not the script itself, but you can use other tools to check if they can connect or not.

This may be due to a firewall, or you need to activate/enable the reader to listen to external devices.
