Cannot upload world to Realms Error 504

I am unable to upload my minecraft world to realms. I have downloaded and re-uploaded my minecraft world multiple times in the past to update it the latest version, or to update the few datapacks I have installed. I have been unable to upload my world the last 2-3 weeks. I have tried uninstalling the datapacks and using MCAselector to delete chunks of map that i had only flown over (mostly in the end) to make the world file smaller, but nothing has worked. I have also tried uploading it on a different computer and removing all the resource packs i use but still haven’t been able to upload my world. I have read on various other forums that others have been having the same issue.
