Failed: Update the IP associated with your YunoHost subdomain


My YunoHost server

Hardware: Old laptop or computer (32-bit)
YunoHost version:
I have access to my server : Through SSH | through the webadmin
Are you in a special context or did you perform some particular tweaking on your YunoHost instance ? : yes
If yes, please explain:
My YNH installation uses a domain, in order to get around dynamic IP address provided by ISP.

Description of my issue

I looked at some of the logs (under Tools > Logs) in the webadmin portal.
At the top of the list was a red “X” and the message “Update the IP associated with your YunoHost subdomain [my YNH domain here]”.
I had not requested any such update; nevertheless, the update had failed. I’m guessing it was some sort of automated update initiated by YunoHost? Full log is shown below.

My main question: Is there anything that I need to do about this error, or will this fix itself?

Thanks in advance for your ideas/help.

Hmokay, but are you still able to contact your server using your domain ?

Yes, I can contact the server via my domain, both from within the local network, and from outside (I have a friend who is one of the users on my server, and he is able to connect successfully from his place).
I can also contact the server via yunohost.local.
Webadmin and SSH both work.
