Indeed, our image uploading system through XMPP used to use the 5280 port. This was changed recently to proxy things through the standard 443 port :) Unfortunately we cannot change the existing URLs that were spread across the whole network so we're keeping an exception for the existing ones. But the new files are now uploaded on this kind of urls https://upload.movim.eu/files/9d94237298995552fa13436420195fbca436dce7/pqIeRmT5iywLGPuFji9pgZsP4VH8mvfIAwWQEFxj/Aurora_wallpaper.png.jpg https://upload.movim.eu/files/9d94237298995552fa13436420195f...
