Hello good day,
I am doing a project with an esp8266 and thingspeak, and when it comes to communicating them from any internet it works, but when it comes to wanting to connect it at my workplace it does not connect, to be more specific it says this:
Is it possible your workplace is blocking the connection.
If you are trying to connect to the device at home, from your workplace - do you have port forwarding set up on your router ?
