Minecraft skin not loading on java bedrock crossplay external server

For some reason, my minecraft skin isn't loading for me on a java bedrock crossplay server, the skin I had did showed up on the pause menu, but when I resumed game, my minecraft skin instead showed up as Steve skin, it happened on 1.20 previously and it still happens on 1.21. I was playing on bedrock. But I'm currently playing on 1.21.0.03
