    it's so hard guys, I delete the 99-loopback.conf file, and use the default configuration file named "87-podman-bridge.conflist".now, it looks right, hope it can work without issue.

    A bit late here, but the exact answer is that .conf (or .json) is treaten as a single plugin config, whereas .conflist can have multiple config. It’s not really clear in any documentation, but it’s here:

    LoadConfList

    func LoadConfList(dir, name string) (*NetworkConfigList, error) {
    files, err := ConfFiles(dir, []string{".conflist"})

    versus

    LoadConf

    func LoadConf(dir, name string) (*NetworkConfig, error) {
    files, err := ConfFiles(dir, []string{".conf", ".json"})
