I was gonna upload a world to my realm but it didn’t work. I tried multiple times but I kept getting the message ‘'Upload failed! (504)’'. I did some research and found out that this can happen due to many different reasons. I trimmed chunks in all dimensions untill the world was barely above 0,5gb. I deleted data packs, restarted the game and my computer, tried a different world slot, used the official Minecraft launcher, closed and reopened the realm and closed all background programs and downloads. I saw many other people having the same issue but never got a real answer why this happens and how to fix it.
