HTTP error when uploading PNG image

I try to upload one of my PNG images to subsite.

If I resize this image below 500×500 px then it works ok. I try with other large JPG files and they work ok. Not sure if this is related to KB/MB size or images sizes as width and height.

We try many things during the chat but none of this work.

I try to contact with the host but they also cannot track issue.

    Hello April,

    I have checked your site and it throws Timout Error on the server level. So this is why there is nothing in the debug.log. However there are errors in the server Error log:

    [Wed Feb 20 02:39:52.843611 2019] [:warn] [pid 1980] [client] Timeout waiting for output from CGI script public_html/wp-admin/media-new.php, referer:

    I checked and this one in lot of cases is the number of MaxRequestWorkers being reached – but this is something that your hosting support needs to check and ask them if they can increase value for MaxRequestWorkers. If they increase it, test this image again and let is know.

    kind regards,


Thank NAME, for their help.
