Shelly devices won't talk to HA since 2023.8.x

I keep getting repair messages about my Shelly devices not able to communicate with HA.

Home Assistant is not receiving push updates from the Shelly device Voortuin stopcontact with IP address Check the CoIoT configuration in the web panel of the device and your network configuration.

Settings are good. Have reboot Shelly devices and HA. But still keep getting the repair messages. Anyone any idea?

I had the same problem, but I could solve it by changing the CoIoT configuration from “mcast” to a unicast configuration. After that (and a reboot of the device) the repair messages were gone.

These are my settings for the shelly devices. But still I get the repair messages in HA.

Got the same problem since the update

Made a issue on GitHub for it.
