Why Does a Hosted Website Return Errors Only for Large Uploads?

Large uploads may exceed web server, application, proxy, or PHP request limits. A timeout or temporary storage shortage can also interrupt processing.

What to check

Record file size and error timing, then compare application limits, web server settings, proxy limits, available temporary storage, and request timeout values. Check logs at each layer.

Recommended next step

Set limits to match a clear business need and test gradually with safe files. Informatix Systems can troubleshoot hosting and application upload behavior.
