Receiving an error 503 message after trying to upload flatsome to wordpress.

I’ve been trying to upload the flatsome zip to wordpress for an hour now and keep getting the same outcome. It loads for a while then shows the error 503 screen. I’ve tried with the zip file from the wordpress file only installation as well as by downloading all files, unzipping, then uploading the parent and child zips (the child zip uploads properly, only the parent one receives this error).
I appreciate any help. Thanks.
