@wangdenkun I get this error on windows, this is my appcast file for second update:

when I open the app it detects that a newer version exists, but when I click on install update, after a few seconds of downloading updates, it says:

[amorenew]

it requires a real url enclosure url="https://github.com/coreybutler/nvm-windows/releases/download/1.1.12/nvm-setup.exe"

the exe will download but it will crash as it is not signed by your key but you will see that it is a URL issue

is my network error
