could not establish sslpsk socket: EOF occurred in violation of protocol (_ssl.c:1123)

Hi I'm trying to flash the KissLink SP200. It timeout after sending the config. The led turned solid after this step. In the `smarthack-psk.log` it shows `could not establish sslpsk socket: EOF occurred in violation of protocol (_ssl.c:1123)`

console log:
```

======================================================
Attempting to diagnose the issue...
An ESP82xx based device connected according to your wifi log.
If this is the device you are trying to flash, another issue may be preventing it from flashing.
Otherwise, it could be that the device does not use an ESP82xx or it did not connect.
For additional information, check the *.log files inside the scripts folder.
Please include these logs when opening a new issue on our GitHub issue tracker.
