421 and empty site

ok so i just saw 2 closed questions similar to this one, but closed 2h ago and i just uploaded my files and tinkered a bit and everything worked fine, website running and everything until some 20 minutes ago… im just wondering is it the same 421 problem or i did something wrong? because this happened when i uploaded my files to dropbox to save precious 000webhost bandwidth, index is fetching files from dropbox instead from 000webhost…so did i break something or what…? + my website is empty now
