Did i break the promise?

Salam. I wanted to ask that i promised Allah that i wont watch porn and since then i have not watched it but there was a video where the person wasnt completely naked but there were sexual acts and i watched it so did i break my promise? I promised Allah about porn but in that video , they were covered so is that considered porn? At that time i did not even imagine that this can be considered as porn because they were covered but when i searched on google they said that if there is sexual act in a video , it is porn. So what shall i do did i break my promise ? I did not do it on purpose. I didnt know that it was considered as porn.
