Why every time I use a hdri skydome it creates weird lights/reflections in some points of the model?

If you watch carefully, you can see weird lights under the roof, close to the beams on the left of the image. I tried everything (roughness of the materials, lumen options etc) and I found out it only happens when I use “backdrop hdri” as a skydome.
