Airlock problem

[teraniel]

Hello! I recently started my brewing journey. I successfully made wine one time, but right now i'm trying to make a 2nd batch and i ran into strange problem. Judging by the liquid inside, fermenting is clearly happening, but airlock isn't bubbling, but also the water level inside airlock does show that some CO2 goes through there. What can be the problem? I checked for leaks, everything is alright, the lid is as tight as it possibly can be. Maybe the lid deformed??
I use plastic container. I also used insulating type to seal potential places where the problem could be, except the lid.

Welcome to the forum.
Many FV's are not 100% airtight maybe the last fermentation was more vigorous than this so you saw bubbles last time but are not this, don't use airlock activity as a measure fermentation has finishing use a hydrometer.

Which airlock are you using if its this type only fill it to here -

If you can get one replace it with a 3 part airlock i find them far better -
