Is there a problem with the Sketchfab site at the moment? I have been trying to upload a model several times over the last few hours (directly from photoscan), and it crashes half way through uploading with the message “Can’t upload model - please check your internet connection”, however the internet connection is fine. I thought it may have been the model itself, so I tried uploading one I uploaded without a problem yesterday, and it failed with the same message. I also tried uploaded while connected to the internet via hotspot through my phone, tried a different computer etc. - all with the same result. I’ll try again tomorrow.
