It also seems like the backup JSON isn't being used. I went back through https://github.com/nroi/archlinux-mirrors-status-fallback to find a backup that didn't contain the line with "protocol: "ftp" and added it to my config file via mirrors_status_json_endpoint_fallbacks but it didn't seem to try it after the main JSON failed.

Thank you for reporting this, @cbc02009!

I've fixed it and released the new version 1.6.9, so flexo is able to handle ftp entries in the JSON file. Flexo should start successfully as soon as you update it. I've also created a separate issue for the fallback not being used (although this shouldn't be a big problem for now, since the JSON file can be parsed now).

Thanks!
