This one has me stumped
concrete floor, besser block walls the door frame on one side is good, the other side is pulling? away from the wall..

Screw and /or pop rivet a flat strip of metal to the brick/metal frame. Push the frame back to the brick and ensure the frame remains plumb and the door will still close.
