[shelly] Unable to parse CoAP Device Description

Hey all,
I have a few shelly 4Pro. All on the same firmware version (20201019-110845/v1.6.6_4Pro@bad181e4) which is the latest. I’m on OH3 but also happened on 2.5.10.
One of them is logging the same error message every few seconds:

Anyone came accross such thing? How to correct it? The other devices dont spit the error.
Thanks for your ideas.

+1 same warning on my OPENHAB3 log:

==> /var/log/openhab/openhab.log <==

EDIT: The actual Firmware of my shelly1 fixed the issue: Shelly firmware 20210115-102904/v1.9.4

same for me. Any news?
