Map not updating Archived · read-only

My archived files are taking hours for even small worlds to upload.  If they do at all.  They sit at 0% and stay there.

I'm having the same problem. My upload sits at 0% for a while. Eventually I get a popup that reads "IO. Error: Error #2038." and then the filename, if that's any help...

Same here. Not the 505 error, a new one. The 505 error is on a new blank page. This error is in a box on the upload page.

What browser are you using? I had problems last week but my last few uploads have all worked fine with Microsoft Edge.
