I am trying to upload an image in sunstone 220.127.116.11, but I cannot. The upload starts, but when the progess bar is at about 4%, there is no further progress, though varying values of upload speed are still displayed. A too large image file is not the problem, its size is only 650 MB. Please help.
I’m sorry that I don’t have more specific information but I remember having a similar issue that was related to too small upload size that I fixed on a front-end config.
With luck, I found the solution myself. The image was not too large for sunstone, but too large for my nginx reverse proxy; so I added
to my nginx configuration and the upload works now.
