Mineraft Realms Times Out When Uploading The Same World Just Downloaded

I rejoined realms, downloaded a world that was already on it. Verified offline that I wanted to use it again and tried to upload it. I have tried for a week of daily upload attempts. Greatest point of upload was 60.4%. I will put it plainly. Its the same world that was on my realm I am paying for. If I cannot reupload it or find an alternative to uploading it I would like a refund and I will continue to play my world offline. I have been playing the same world since 2012 so Id like to continue with it. Let me know what the alternatives are. I reiterate its the same world that had been on my previously dormant realm account.
