What happens when you press the reset button? Did the factory reset do anything?

Could you explain what you did in order to fix it, so that others can use this in the future?

I could be wrong but I think a factory reset fixed it. I think @Omar may have accidentally performed the operate incorrectly and, after reviewing the docs, performed it successfully which fixed the problem. @Omar is this correct or did you do something else?

For easy reference, this is how to perform a factory reset: [http://docs.spark.io/connect/#appendix-factory-reset](http://docs.spark.io/connect/#appendix-factory-reset)
