in the function (s *IdentifySlow) Identify(): in case you found the cloud the function returns and closes the channel
but other goroutines will try to write to it... you need to add defer and recover OR safe write to channel

func (s *IdentifySlow) Identify() (string, error) {
detected := make(chan string)
defer close(detected)
.................
for range prov {
d := <-detected
if d != defaults.Unknown {
return d, nil
}
}
return defaults.Unknown, nil
}
