"Failed to upload pack s" when attempting to add behavior or texture packs to realm

It's Been Like This For a few weeks now and figured it might of sorted it self out by it self but nothing has changed, ive been trying to create a new season for my realm and everyone been looking forward to but the only problem is that everytime i make a change to the "Game Settings" Or Add a "Behavior/Texture Pack" it will say "failed to upload pack s" ive even tried with Minecraft Store Texture Pack and it still wasn't working
