Uploading Plugin/Theme in WP results in Secure Connection Failed

WordPress Nginx Apache Ubuntu 16.04

I am using Ubuntu 16.4 nginx as a reverse proxy and Apache php-fpm with varnish for caching. SSL traffic is being routed through nginx and any non ssl traffic is being redirect to https in the varnish config.

When I try to upload a plugin that is over 2M I get various errors relating to the server

In firefox I consistently get Secure Connection Failed

In Chrome I get...

This site can’t be reached

The webpage at https://domain.com/wp-admin/update.php?action=upload-theme might be temporarily down or it may have moved permanently to a new web address.

If I try to upload something to the media library I get http error if the file is large if the file is not over 2M it uploads fine.

I have increased my limits in my php.ini file and it is reflected everywhere...

Maximum upload file size: 128 MB.

the post size also...

Anyone have any insight?

I was able to get this working. Turned out all I needed to do was add the following directive to the nginx vhost file...


 server {
      client_max_body_size 100m;

    location / {

This seemed to work for me but I am not sure why this is needed when I am setting things in my php.ini file.
