Lost Connection to Vitoconnect 100 OPTO1

[Mayone]

Good morning, for a few days now I've been unable to contact the Vitoconnect 100 OPTO1 module, either via the ViCare app or via HomeAssistant. I checked and the module is correctly connected to the network, and I see that the firewall sees requests to the Viessmann cloud, but nothing appears on the app or HomeAssistant. I've already tried disabling and reactivating the Wi-Fi network, but to no avail. Can you give me any suggestions? Thanks!

please try to power off and power on the Vitoconnect modul, for me its solved connection problems

In your opinion, why did I take a remote management module? Maybe because the installation is 300 km away? Unable to disconnect power.

I managed to send someone home to restart the module and it worked for a week. Yesterday, in conjunction with the update of the app on the phone, it stopped working again. Obviously the module is connected and detected by the dhcp server. Worse and worse.
