Trouble uploading worlds Error 524

Hi, I am having trouble uploading my world in import wizard, it keeps giving me error 524.


And the progress bar is stuck like this for a long time.

Any ideas?

Hi there :wave:
Reposting from #forge-support on the Forge Discord:

A 524 indicates a timeout, this can happen if importing data that is particularly large or has very large single files (or files which are very tightly compressed) that struggle to compress during the upload step.
I’d recommend having a look through the folder that you’re uploading, and if it includes any large single files, exclude them from the import. This can often be the case if there are intermediates (such as photoshop or krita files from assets) stored in the worlds’ folders
