I got a new computer, and rebought Minecraft java edition on this one, but logged into my previous Mojang account on the new computer. Everything was working fine until I decided to change my skin. I changed my skin, then when I logged onto my world my skin was set to Steve. I thought it was just my skin, however when I logged onto a public server, I couldn't see anyone's skin, all of them were either Steve or Alex. The internet I have is fine, as my brother doesn't have any issues when he plays on his game, and I have tried doing different skins, changing them on both the game and the website. I've tried everything I can think of and still cannot figure out what is wrong with it. Please help!
