[bug] How to increase allowed attachment size? FILE_SIZE_LIMIT not working

[Plorenzo]

Is there an existing issue for this?

• [X] I have searched the existing issues

Current behavior

When a image bigger than 5MBs is uploaded the system give an error. File size too large. Please select a file smaller than 5MB.

To increase this limit, I tried to change FILE_SIZE_LIMIT to 15728640 in .env a restart the services, both with ./setup.sh script and directly docker compose up -f and after the services are up again the same error happens when trying to upload a big file.

Steps to reproduce

Create an issue an try to upload a 6MB file

Browser

Safari, also in Firefox

Version

Self-hosted

@Plorenzo I had also to increase the Nginx max body size:

I just check and the nginx config in the container is correctly updated already from the .env file

@Plorenzo hope you have changed the .env file

@mguptahub please refer to my original comment

I ran into this too. Good news, read through.

I have verified that setting FILE_SIZE_LIMIT and restarting updates the nginx.conf in the proxy container.

For example, mine looks like

...
        client_max_body_size 134217728;
...

When I upload a file that is 20 MB, it failed with a 413 Request Entity Too Large. But, it would not show up in the "proxy" container logs. Why is that?

Turns out, I had to update the outer nginx layer that reverse proxied towards the container, as the outer nginx layer handles HTTPS with certbot.

(host nginx) -> [docker nginx proxy container -> api container]
 ^^^^^^^^^^
Failure was in the host.

If you run into this, check every layer of your implementation!
