I just recently updated to 8.8.3 and for some reason, all of my modules now say "No available releases found". Also the one module I had that did report "No available releases found" (Video Embed for google drive), is now saying that that module is up to date. It is like they switched somehow when I updated. I might roll back but the site is currently working just fine. Any ideas?
Clicking "Check manually" once on the Available Updates page will resolve this issue.
