Yes, it's a whole new image and resets everything to factory. This is not a critical update so if your system is working and you're happy, leave it!

The debugger caught an exception in your WSGI application. You can now look at the traceback which led to the error.
To switch between the interactive traceback and the plaintext one, you can click on the "Traceback" headline. From the text traceback you can also create a paste of it. For code execution mouse-over the frame you want to debug and click on the console icon on the right side.

You can execute arbitrary Python code in the stack frames and there are some extra helpers available for introspection:

dump() shows all variables in the frame
dump(obj) dumps all that's known about the object

Hi, this is indicitive of CGMiner crashing, could be pool connection, internet connection or mining hardware related. For optimum diagnostics, you need to SSH in to the unit and see what CGminer is doing and if it is running, etc. This is all documented early on in this post.
I have helped several people lately that have put in Ethereum wallet addresses in the config page which causes CGMiner to fail immediatley which in turn crashes as such.

Can you go to the IP address of the device (you may need to look this up by doing an IP scan on your network if the OLED screen isnt working), go to the IP of the SmartHub in your web browser (note, the machine you are accessing the Smarthub from must be on the same network). I then want screenshots of everything you see on the screen.

If you are tech savvy, go back earlier in the post and look at SSH'ing into the unit and seeing what is causing CGMiner to crash.

Who did you get the SmartHub from?

Cheers

Hello Everyone - I just got this unit and it has been running fine all night.  This morning I came in and the hashing stopped.  Went to the web browser and am getting this below.  Suggestions??

Note:  I am a total NOOB when it comes to all of this.  Please be kind!
