Symptoms
Using Smart form for uploading a file to SharePoint but form will not accept file
Diagnoses
We increased size to 100mb but somewhere around 30MB we get the error “The file could not be uploaded. The network might be down or the file size larger than the maximum allowed”. if I try a larger than 100MB file it says 100Mb is max. Are there other settings we missed.
Resolution
Updating the web config as follow per following Community post resolved the issue.
