F-Droid Not Downloading Updates

[startac4]

F-Droid has stopped downloading updates to my main cellphone. It repeatedly says (when I check) everything is up-to-date. But it does download updates to my travel cellphone. The programs on my main cell phone - e.g. Duck Duck - are way out of date. Both phones appear to have the same settings - do updates with Wi-Fi. Wi-Fi IS active on both phones.

What is your main cellphone? Do you have VPN?
