Problem trying to connect to THINGER_SERVER

The problem is that when I change the name of the THINGER_SERVER for another one, it does not connect, it shows the message of the attached image. But if I leave the default name “”, it connects, but at the free of charge of only 3 devices.

The problem is that when I put the name of my payment host, it gives this error.

Hi @Bryan_Miguel_Chaves

Can you reupload the image of the error?

In the meantime I would ask you to check out the troubleshooting page:

Keep in mind that the definition of THINGER_SERVER should be at the top of your code, as well as the device should be created with the same id and credentials that is on the code.
