Mobile Charger 110v Flashes Red Twice - Help

Hey all,

Last week I came out to my garage and noticed one wall not receiving any electricity. I've had my mobile charger gen 2 connected to this wall daily without any problem. I then tried the charger in multiple outlets but it streams green once then flashes red only on the T twice.Manual shows that its a grounding issue and so is my vehicle. The wall is still out of power. Maybe blown fuse? But can my entire house all of a sudden not be grounded?

Has anyone experienced this? The wall still has no electricity. Not sure if that ruined my charger somehow.
