- Fri May 11, 2018 10:46 am #75884 Hi i have a problem: My code is working fine , but when i disconnect the board (power off) seems i can't to connect again with the webserver. And to work againg i need to load the sketch.

Check connection
Verify proxy and firewall
Run Windows Network Diagnostics
ERR_CONNECTION_TIMED_OUT

Whats is causing that error?
