Currently, we can only upload files smaller than 2MB to the Opal server. We adjusted the parameters and followed the instructions provided in [Opal properties file](https://opaldoc.obiba.org/en/latest/admin/configuration.html#miscelaneous-configuration), the changes did not take effect after restarting the server. Could you suggest a potential solution to this issue?

The error could be due to a proxy in-between. Check with your IT dept.

Hello @Yannick,

Thank you for your response. I’m running the DataShield Docker image on my local machine and have modified the Nginx parameter `client_max_body_size` to 1G. This allowed me to successfully upload a CSV file via the Opal UI, and it was correctly stored in both the project and the project table.

However, I encountered an issue when uploading files in other formats. The Docker environment crashes during these uploads.

Additionally, while attempting to upload a file to a project table via `opalr`, the file successfully uploads to the project folder, but I observe an error during the unsuccessful table upload process. The Docker logs display the following error: org.obiba.opal.web.FileResource.uploadFile(java.lang.String, javax.ws.rs.core.UriInfo, javax.servlet throws java.io.IOException, org.apache.commons.fileupload.FileUploadException)
