Fresh install, domain not working

Here are the results of ‘ls -a’ in that directory, if I should check another way let me know

plumbus@plumbus:~$ cd /etc/yunohost/dyndns
plumbus@plumbus:/etc/yunohost/dyndns$ ls -a
.  ..  Kplumbus.nohost.me.+157+21297.key  Kplumbus.nohost.me.+157+21297.private  zone

I ran the code above as root and I got the following error

root@plumbus:/etc/yunohost/dyndns# yunohost dyndns update -d plumbus.noho.st --debug
55   DEBUG loading actions map namespace 'yunohost'
59   DEBUG extra parameter classes loaded: ['ask', 'password', 'required', 'pattern']
60   DEBUG initializing base actions map parser for cli
61   DEBUG registering new callback action 'yunohost.utils.packages.ynh_packages_version' to [
'-v', '--version']
5124 ERROR An instance is already running

Thanks again for your help

edit:
I reboot the server and rand the above dyndns command again, here is the result
