No avatar after upload

Hello. I cannot upload a new avatar picture via user profile. Picture uploads as usual, but after it's finished, I see just icon like image is missing. What may this be caused by?

Need a few things, can you provide the image you're trying to upload. Also can you provide a console log Step 4 .

Seems like I sucsessfully uploaded my avatar from another PC. I had (and I still have, just checked it) this issue with any image, so I don't think it's something image-dependent.
