Hey, @sportisans
The timeout error you are seeing is a result of the server the photos are hosted on (the product suppliers website) are taking too long to communicate with our uploading tool, which causes the error. This is why when you tested an image from somewhere else, it worked.
This is generally because we have soft limitations in the filesizes and resolution. If it didn’t time out, it may fail after we download it because of excessively large filesizes or resolution.
There wouldn’t be much we could do on our end to “allow” or “extend the timeout time” on our end. Your best option would be to either try again with the photos hosted where they currently are or download and host the images from somewhere else.
That being said that import is extremely large. Our system generally prefers 10k and below lines of a CSV at a time. It might be a good idea to break up that single file down into a dozen or so smaller files.
If there is anything else I can help you with, please let me know.
