Offside headlight problem

Im having a problem location the reason why my offside main and highbeam headlight isnt working,
I bet it's a simple problem, but im just sratching my head at the moment.

I tested the bulb, it was fine
I've tested and check the fuse behind the nearside headlight, that's fine
Ive even checked the back of the plug of the headlight and there's 100% no electric and its not corroided

Plus the highbeam indicator on the dash doesnt illuminate, but the nearside head light works perfect
