Your problem is that most likely the Nozzle is not tight. Check the proper installation instructions for your hotend. It could also be the the threads got stripped. If you have a hotend where the PTFE tube goes all the way to the nozzle, take the PTFE tube out. Check the end make sure there is no damage and its cut straight. Then turn out he nozzle 2 turns, insert the PTFE tube all the way then tighten the nozzle to the specifications of the hotend. If its all metal check the assembly instructions. Nozzles will get loose after some printing and then you get leaks
