I have played on minehut servers for quite some time with my friends. We decided to use minehut because it was a good free server operator. Recently when 1.16.1 released minehut decided to patch both tnt duping and breaking bedrock with would ruin a lot of things in our world.
I decided that we should make a backup and start a new server untill they enable it again, but when I tried to download the world with /dl world world it didn't work because "failed to upload file". Then I tried with the Nether and it didn't work either. But when I did it with The End it worked.
