unable to connect to Vitoligno 300-C

[lb_ch]

Since 4 days, the connection between Vitoconnect OPTo2 (7637415074703240) and Vitoligno 300-C stopped working. Vitoconnect was still with the "white house logo" but doesn't update/upload the data anymore.

What I did :

- reboot vitoconnect

- factory reset vitoconnect

- unpaired vitoconnect

- uninstall vicare app

Now, when adding back the vitoconnect, it cannot communicate anymore with Vitoligno 300-C. I don't have any information on the homepage and the app says that I have to wait that all the data are loaded.

In the settings, I don't see the Vitoligno 300-C anymore. Only the communication module. Can you help me ?

Initally, It stopped working since 3 july 14:46.

Is it maybe related to ViGuide update 2.46.3 that happens also the 3 july ?

I don't think the problem is due to hardware malfunction. I think it's on Viessman server side.
