Manual Uploads - Entire file not processed
When running a manual upload and the entire file is not processed, here is what to look for
We have a maximum upload time of 120 seconds for manual file uploads.
Because of this, sometimes, depending on the size of the file or the speed of your connection, a manual upload will take longer than 120 seconds.
A rule of thumb for a high-speed connection: If the file is over 20 megs, it may take longer than 120 seconds to upload.
