When in the Launcher, the skins menu will repeatedly say 'unable to load skins' even after restarting the Launcher

I made a new skin for myself, and then tried to open the Java Edition skins menu, and it said: 'Unable to load skins'. I clicked 'try again' and it didn't work. I then spammed the button and then restarted the Launcher, tried again, and it still didn't work. Then I came here, and...yeah.
