Updates Process Seems to Hang

I have 26/35 sites in Central, and Updates have been working fin til about a week ago.
Now, when I do “all Updates”, teh progress bar hangs about halfway up the slide. Two days ago, I removed the updraft link to the site that hung.
But now it’s hanging up on a different site, and doesn’t seem to finish.

Here’s a snapshot:https://www.screencast.com/t/eQGcMCIUB2R

I can do individual sites, and updates work at each location’s wp-admin, but this one is being weird…
Thanks for help?
