Ender 3 v2 nozzle stucks after a while

  • PS: this is my second post about same problem. After i submitted the post, it is removed some how.

    Hello there,

    I am very new at 3D printing domain and , just bought Ender 3 V2 and i would like to ask about my unfinished printing problem.

    The SD card which is coming w/ the package consists two example gcode files.
    After i started the printing for cat-3.5h.gcode;

    First 1 hour, printing went almost perfect.
    After that; nozzle started to not drop any filament and there was different noisy sound on extruder side.
    Here is the video:

    I thought nozzle is stucked and stopped the printing, cleaned up the nozzle and started over again.
    But same thing happened again.
