Sync issue, stop do update

[#1]

I always use sync in my catalog with the LR cloud.
I have sync close to 200.000 images and sometimes take longer to update the new image or changes I made in some photos in the desktop LR classic.
But now they show they are sync around 600 images and nothing happens. 

I have enough space in my Create Cloud account.
I still with this problem at the list for the last month.
Thank you in advance for any help

Screen shots of what you are seeing will help solve the problem you are having.

Also you do not Sync your Catalog. You Sync Collections which might contain all the images in your catalog but it is Not the Catalog file that is being synced.

So please state the steps you are taking to sync images from your LrC catalog with the Lr Web system.
