On BudgetAir/Flight Network, I could only find one MF flight on your given date and it is the one with a 13-hour layover at AMS. Not sure it is worth it though.
On Justfly, there are many choices available but you will need to settle your ticket in USD.
But it is quite strange that all fares for the flight I am looking for disappeared on all OTAs...only Justfly seems to be able to find it.
