Judging by the IP address 169.254.x.x, it appears that your Viessmann gas boiler cannot receive a correct response from your local DHCP server. What IP address are you using to log in to your router - 192.168.0.1 or 1.1? Then, your Viessmann gas boiler should be able to receive an IP address starting with 192.168.

It suddenly started working.

It suddenly started working.

Hi, Polish Viessmann support informed me that they had a very long maintenance window, but everything should be working now. I reset the OT2, but it's still not functioning correctly. This time, I was able to capture more logs and I see that the OT2 is trying to download firmware with the request GET /firmware/hb2/7637414_Vitoconnect-100_OTOL2.version, but the Viessmann server is closing the connection. DHCP, DNS, NTP work so OT2 has internet access.

Chris34 · ‎16.07.2024

It sounds like more users in Europe are affected. I analyzed my router logs and noticed that the OT2 is connecting to Wi-Fi, communicating with NTP (time) servers, and using my ISP's DNS. It successfully resolves mgmt.viessmann-platform.io and establishes an HTTPS session with Viessmann servers, but then the communication suddenly stops. As a result, I only see the "Updating" screen in the ViCare app (and red wifi icon) 10:05:18.767224 IP 192.168.0.158.55823 > nsx2.internetunion.pl.53: 42087+ A? mgmt.viessmann-platform.io.

Sure, I understand that. However, I am not the author of this thread. By looking at the forum, it seems there are multiple recent threads mentioning the same issue with the red WiFi icon. If you assist the author of this thread and others requesting help in similar threads, you will automatically be helping me as well.

Chris34 · ‎15.07.2024

No result. Still see red wifi icon.

I am using a Vitodens 100 with Vitoconnect OT2. For about a week, Vitoconnect has been unable to connect to Wi-Fi, indicated by a red Wi-Fi icon on the device. I have tried the following troubleshooting steps: Reinstalling the Android app Clearing the app's data and cache Resetting Vitoconnect (holding the button on OT2 for 30 seconds) Powering Vitoconnect OT2 on and off Connecting Vitoconnect OT2 to different Wi-Fi routers and networks Re-adding Vitoconnect OT2 to my Viessmann account multiple times I have also collected Vitoconnect logs, which I am attaching to this email. The log file contains multiple errors.

Hi I have same issue. Please check Viessmann Climate Solutions Community - Viessmann Climate Solutions Community I attached device logs too.

Hallo, ich benutze einen Vitodens 100 mit Vitoconnect OT2. Seit etwa einer Woche kann sich Vitoconnect nicht mit dem Wi-Fi verbinden, was durch ein rotes Wi-Fi-Symbol auf dem Gerät angezeigt wird. Ich habe die folgenden Schritte zur Fehlerbehebung ausprobiert: Die Android-App neu installieren Die Daten und den Cache der App löschen Vitoconnect zurücksetzen (den Knopf auf OT2 für 30 Sekunden halten) Vitoconnect OT2 ein- und ausschalten Vitoconnect OT2 mit verschiedenen Wi-Fi-Routern und Netzwerken verbinden Vitoconnect OT2 mehrfach zu meinem Viessmann-Konto hinzufügen Ich habe auch Vitoconnect-Logs gesammelt, Die Log-Datei enthält mehrere Fehler.
