OK, yep, see SSL Certificate Error. In this case, the relevant address would be https://repo.zotero.org. Network connection in Zotero may not be working for you at all, which would break lots of functionality — and you should be seeing an error icon to the left of the sync icon at startup if that's the case. (It's also possible only some requests are being blocked by your IT department. Are you successfully syncing from this computer?)
Update: I took my computer home and updated the translators from my home network. That appears to have fixed the problem. Syncing was working from both locations. It is only updates to both the translators and the main Zotero program that seem to be an issue from my work site.
I can't get any data from this "sciencedirect" page. I read the comments. You say reinstalling the translators solved the problem. Where are the translators on the internet? I am making a remote connection from my computer to my university. I am using vpn. Whenever I use vpn I get this error.

(You don't need to, nor should you, manually download translators)
