library is not syncing

We are using lybrary to work with assets in our company, it`s in use by ~15 people, but from recent time it stoped syncing and we can`t upload any new mockups in it. How can that be fixed? https://www.adobe.com/files/libraries/urn:aaid:sc:EU:e3dbae26-4fc8-44de-80e1-7f4d4d5334c9
