Arena Troubleshooting: File Upload Error
Last updated: February 2, 2026
In some cases, users may encounter an error when attempting to upload files. This can prevent the file from attaching successfully or stop the upload process partway through.
What’s Happening
File upload errors can occur due to browser-specific behavior, file size limits, or the number of files being uploaded at once. These issues may vary depending on the file type and client environment.
Recommended Steps
If you encounter a file upload error, the following steps may help:
Try a different web browser.
Reduce the file size.
Upload fewer files at once.
If the issue persists, you may need to continue without attaching files for the time being.
