Nira will label your upload as "Stalled" in situations where your network connection encounters a momentary or lasting disruption, if you close the browser tab during an upload, or if you modify a file while it is still in the midst of being uploaded.


You may find it beneficial to examine your Task Manager (for MS Windows users) to determine if there is any outgoing internet activity.  In the provided screenshot, there is a steady upload activity at a rate of 120 Mbps.



Stalled uploads FAQ

Q. If an upload is Stalled, can it ever recover?

A. Sometimes, yes. For example, if your PC loses its internet connection for more than 5 minutes during an upload, its status will be listed as "Stalled". If your internet connection comes back online, the upload may recover and its status may change from "Stalled" back to "Uploading", and will successfully complete. There are circumstances whereby it may never recover. For example, your upload will not resume if you closed/ refreshed your browser tab or closed the uploader application (e.g., RealityCapture or 3DF Zephyr) during upload.

Q. My asset upload stalled, and I don't think it will recover. What should I do?

A. If your Internet connection is working fine, simply try the upload again. Nira will automatically determine which files were previously uploaded, and avoid re-uploading them. It's a good idea to close any existing Nira browser tabs before trying your upload again.

Q. Can stalled uploads be removed from the Upload Jobs page?

A. The Upload Jobs represents a history of all of your past uploads, including any in-progress, completed, stalled, or failed. There is currently no method to delete an upload job entry from the Upload Jobs list.

Q. Do you have any tips for avoiding stalled uploads?

A. Yes:

  • Close running applications that may be accessing your files. It's possible that another program (e.g. RealityCapture, Blender, virus scanner, etc..) may modify or lock some of your files during upload. Make sure to close any application that might be accessing the files you're attempting to upload.  It's best to keep any application that may be accessing these files closed until the upload is finished.  Another workaround is to first copy the files to another directory (preferably a local and fast SSD/NVME drive) and upload from there.
  • Upload from internal storage. It's always best to upload from a internal drive than using a network or external drive.  Network and external drives are not as reliable and can become inaccessible during an upload.  This can happen because of faulty cabling, driver, or OS issues.
