For some reason, cryptolend do not create any loan even though I have tons of money available and my loan limit is way below the going rate for the loan.

It's been hours and the money is just sitting there. Sometimes some loan are closed and cryptolend start creating new loan. It simply stop.

I checked that it may be because of "wall"

What I usually do if I manually create loan offer is I do not offer something on top. For example, lowest rate may be 16%. I don't offer 16%. I offer about half a page below. If no body borrow, I lower my rate again. Usually someone borrow.
