anfieldleung on "[Plugin: ILAB Media Tools] Nginx compatibility"

Hi,

I got WP multisite running on php version 7.0.8 , WP 4.5.3, ILAB Media Tools 1.0.4. The plugin was activated on a subsite with S3 credential configurated. The images failed to upload to S3 no matter "Automatically uploads" checked or using the S3 importer. However, there is no error message, the images still on local server. May I know the reason why? Thank you.

It's certainly not an nginx issue. Do you have php error logging enabled? Can you paste in some logs when performing the upload?

Yup, the error log is enabled, but not much information show.
The most relevant is this
2016/07/14 17:06:44 [wa] 4995#4995: *487 an upstream response is buffered to a temporary file /var/cache/nginx/fastcgi_temp/6/03/0000000036 while reading upstream, client: 10.109.248.181, server: www.hermes-ottoint.com, request: "GET /productinfo/witt-weiden/wp-admin/upload.php HTTP/1.1", upstream: "fastcgi://unix:/var/run/php-fpm/php-fpm-scarp01.sock:", host: "www.hermes-ottoint.com", referrer: "http://www.hermes-ottoint.com/productinfo/witt-weiden/wp-admin/media-new.php"

My server is within intranet able to access Inteet but unable to being access from public. Is it the reason behind? Is there any response or connection is needed from S3 back to my server?
