Error WebControl connection [SOLVED]

[Antonino Ferreira]

Good morning, I am not able to set up access to WebControl, when I select "validate settings" in the settings displays the error:

Code: Select all

Error #204
- Syntax error, malformed JSON
Your controller sent an answer with wrong format but the changes can have been saved.
Please refresh this page and check the changes.

The problem is in the configuration or on my web server?

In the browser using the local IP information appears.

Thank you.

Hi!

This error can be related with noise in your power supply.

In the tab "Webserver" find this part and uncomment:

Code: Select all

      /*#ifdef DEBUG
            Serial.print(F("Socket:"));
            Serial.println(i);
        #endif*/

After upload look for serial monitor to check if you can see something like this:

Code: Select all

Socket: 0
Socket: 1
Socket: 2
Socket: 3

I had this problem and was solved adding a capacitor between GND and VIN.

Show me a print screen of your browser using local IP to see if something is wrong.

Are you using latest version available on Github?

Best regards.

Presents no socket:

I'm already using the latest version available on Github.

Thank you

The Json format is right.

There other server replying the requests, I can see this answer:

Code: Select all

string(45) "
It works!

Try the port 5000 because the 80 is blocked by many providers.

[Antonino Ferreira]

The problem is that when I check other ports in http://ping.eu/port-chk/, only port 80 is open, the others are all closed.

[Fernando Garcia]

You did port forwarding in your router?

[Antonino Ferreira]

Friend, I changed the port to 5000, works with the local IP but the door is not open, now in WebControl displays the error:

Code: Select all

Failed to connect to 177.84...... port 5000: Connection refused.
Your controller is not responding.
Please check if your ethernet cable is connected.

Thank you

The problem is on port forwarding in your router.

Can you show a print screen of the settings in your router?

[Antonino Ferreira]

Hi Fernando, my router is an apple airport extreme, that is the port setting configuration. If this router does not work, which the router to recommend?

[Fernando Garcia]

Hi!

Firstly you should check with your provider to know if the ports are not blocked.

Best regards.

[Antonino Ferreira]

Ready friend, problem solved, lacked release the door in internet server. Now it is working 100%.

Thank you.
