Bombarded with "Could not update IP address to DynDNS"

[Tio]

My YunoHost server

Hardware: VPS bought online
YunoHost version: 4.1.7.3
I have access to my server : Through SSH | through the webadmin | direct access via keyboard / screen | …
Are you in a special context or did you perform some particular tweaking on your YunoHost instance ? : no

Description of my issue

I got hundreds of emails for the past hours with this message “; Communication with 2001:910:1410::1#53 failed: operation canceled
update failed: FORMERR
Could not update IP address to DynDNS”

Is this a problem with my server or ynh ones? I is because I use a nohost domain that was provided by ynh at installation? Is this error something to be concerned about?

I got the same error on 2 of my servers actually. https://paste.yunohost.org/raw/xayukijabo + https://paste.yunohost.org/raw/dopayipiso

Hello

IIRC, this is a known yunohost related problem, which happens on specific hours : servers can’t contact properly Yunohost.

If your server have a static IP, you can desactivate this cron job which update dyndns.

Can you try a yunohost dyndns update anyway ?

Hello,
Yes I have a static IP. How to deactivate this?

$ sudo yunohost dyndns update

You can use this command : yunohost dyndns removecron

About your issue, not sure this belongs to Yunohost. I just successfully ran a yunohost dyndns update on my own server.

Ok I removed it since we don’t use a dynamic dns anyways and I was getting emails every minute. I hope that’s ok by removing it. Thanks a lot!
