# Upload limit on internal server

Asked by amilles on 2026-01-06

Dear OpenForis Team, 

we are currently about to move a larger survey from openforis-arena.org to our internal openforis-arena server. It exceeds the 1GB limit for uploads (its almost 2 GB). Is there a way to increase the upload limit for internal servers (i.e. some config value)? I figured out, that I could remove image files, but this would be a last resort.  

Thanks & best wishes
Alex

Dear Alex,  
This issue has been (finally) fixed with the latest version of Arena, v2.3.12.

Dear Alex,  
In the next version of Arena, 2.2.14, that will be released by the end of this week, we will allow setting this limit using an environment variable, `FILE_UPLOAD_LIMIT` (in bytes) so you will be able to specify the limit you need.  
Many thanks,  
Open Foris Team

> Dear Stefano, Thanks for the quick response. Looking forward to the solution and will let you know here! (amilles)
> Dear Alex, The new version is ready. Please try to install it in your server and let us know, thanks. (Stefano (OF))

Dear Stefano, 

thanks again for the quick reaction! It took us some more time to test it. 

We parameterized the envfile as follows:
## Maximum file upload size in bytes (default: 1073741824 = 1GB)
FILE_UPLOAD_LIMIT=4294967296

However, when uploading larger files (e.g. importing a survey with 1.7 GB), it still shows the previous error. Besides that, the message in arena did not update and still shows:

"Drag and drop a file here, or click to select it
(Only .zip files with a max size of 977 MiB will be accepted)"

Thank you, Stefano, for the quick update. We updated to 2.3.11 but, unfortunately, the error remains the same.
