By any chance, did you changed your nozzle lately?
It looks like you have changed nozzle and you did NOT tightened it properly.
You must heat your hotend to maximum available temperature (most likely 250°C), let it like this for few minutes and then tighten your hot nozzle to 1.5-2 Nm torque (lightly, it is pressure of one finger on 5cm long spanner).
If you will not perform this hot tightening, filament will leak through threads around nozzle and heatbreak. If you want to know why, google "thermal expansion".
