Can't trade nx items

Yesterday bought 3ap resets and i try to sell them to people but every time i try sell it says trade unsuccessful. Ive traded nx items.

Edit ( Im lvl 66)

Edit: I've tried relogging and try again 8hrs later no fixeruno
Edit: not on this account but my mule

 

Probably because you're not level 50 yet.

 

Ops forgot to add im lvl66, ive traded before and never had a problem but now i do

 

Just bugged then. Try relogging, it should fix it.

 

Relogged like 20 times and waited 8hrs :O

 

Huh. Weird. Did the person you tried to trade em to relog too?

 

Yep tried trading 3 different people

 

Then Idk. Sorry man. :/
