Question - Uploading (413) Request entity too large

Using GMS2.0 v
I cannot update one of my existing packages (project). I also tried manually but it has been 'processing' for well over a month now.

I get the messgae Package upload failed: The remote server returned an error: (413) request entity too large.

Sadly, it looks like the marketplace is a bit hit-n-miss for me lately.
