Hey I've been contacting admins and mods but they can't seem to fix the problem. I've been trying to update my skin for 3 weeks now and for some reason they just won't let me update it. Every try they say can't connect to mojang or my account isn't premium ( I'm premium)... I Hope you guys can fix this bug and thank you very much....
Must be a problem with your launcher or something, cause I changed my skin yesterday and it worked! I don't know tho... @Arjenpro
Hey, this happened to me as well, I fixed this by waiting a few days and retry it again. Hopefully, you're going to have it fixed soon! Kind regards, Killer
