CalDav problem: SOGo & emclient? Calendar deselected / disappear again and again

Hi there,

since 1,5 years we use SOGo Server / Mailcow and emClient (Version: 8.2.1473 (04b618f)) with IMAP, CardDAV and CalDAV (automatic configured) and so far everything has always worked.

For about 2-3 weeks, subscribed (shared) calendars and own calendars have suddenly been ticked off / disappear for a short time completely from the overview and a few minutes later the reminders of old appointment entries appear and you can select the calendars again.

Even if you switch to the calendar tab, 95% of the time all calendars are deselected and you have to select them again. 5 minutes later everything is deselected again …

When the calendar is displayed, new entries can be made as well as deleted.

Thanks so much & best regards.

Hi @Picannick

Who is your internet connection with and what speed?
Is it a stable connection?
Do you connect with Ethernet or WiFi?

Hi skybat,
many thanks for your response.

We are at Vodafone and have a 1GB line and all computers are connected via Ethernet.
A few weeks ago there were a few problems with the connection, but the line is now stable.
