I have the same charger in my shop I didn't use it for over a year and when I finally decided to hook it up I was able,to get right onto Blinks network that's when things went south.
Blink updated the software in the charger and locked me out they thought,the charger was part of a pay charging service and locked me out after two weeks of phones they finally downloaded software to the charger and that set it back to a owner charger.
That a couple months ago a phone call to Blink is all I did
By the way if you don't mind what did the charger cost you . Mine is on a metal stand that Blink makes which can be secured to concrete the stand has to,weigh 50 Lbs
