So I've never had a problem uploading instructions before but tonight I can't seem to do so. When creating a new MOC I get to the step where I add instructions and I select the Premium (Rebrickable Hosted) option and then select "Add File". On the next screen I scan to the file I want to upload for instructions and hit Upload and this is where the problem occurs. It just sits and spins for about 2 minutes and then comes back with an Error 504 in the upper right hand corner. I've tried uploading multiple files, multiple file types. Tried three different computers from three different internet connection. Tried creating a new MOC. None of it will fix it. Even tried using from the uploading "from URL" option and had the same result. Any suggestions?
