Cannot fetch packages during migrate

I ran into this error when running raco pkg migrate 8.14. Can someone help me figure out what's going on? I can visit the host through a browser on my device. I don't have a VPN or proxy or anything. I'm on termux on Android if that matters.

Wondering if it's related to this recent change which I see mentioned here: Release Announcement for v8.15 - #21 by shhyou

I didn't get this bug when migrating on a different machine in my network. So I don't think it's network conditions. That was a Linux desktop
