Is there a problem with the Blynk server?

Why don’t you just try the free version?

Yes.

In Debug mode, “<” indicates data sent from the device to the server, like this…

which is a 1D hex (29 decimal) “BLYNK_CMD_HW_LOGIN” request, followed by your Auth token

and “>” indicates data received from the server, like this:

which in this case is a C8 hex (200 decimal) “BLYNK_SUCCESS” response message.

So in effect the device is asking the server for permission to log-in, with the Auth token as the credentials, and the server is responding with Okay.
