-Content length of text and files managed by the application are limited by default. Before TheHive 4.1.1, they were set to very small values.
-Default values in TheHive 4.1.1 are set with these default parameters: 
+Content length of text and files managed by the application are limited by default.

+**Before TheHive v4.1.1**, the Play framework sets the HTTP body size limit to 100KB by default for textual content (json, xml, text, form data) and 10MB for file uploads.
+
+**Since TheHive v4.1.1**, these values are set with default parameters: 
+
+```yaml
+# Max file size
 play.http.parser.maxDiskBuffer: 128MB
+# Max textual content length
 play.http.parser.maxMemoryBuffer: 256kB
 ```
 
-If you feel that these should be updated, edit `/etc/thehive/application.conf` file and update these parameters.

+!!! tip
+    if you are using a NGINX reverse proxy in front of TheHive, be aware that it doesn't distinguish between text data and a file upload. 
+
+    So, you should also set the `client_max_body_size` parameter in your NGINX server configuration to the highest value among the two: file upload and text size defined in TheHive application.conf file.
