Hello, I am running SOGo on Debian trixie with the nightly builds and since the latest manual update this week-end I cannot open some of the received emails. The SOGo interface just shows 'Request failed' but the logs show this:

This does not affect emails viewed on the mobile phone, they can be viewed without problems. Let me know when this is fixed in order to update my SOGo server and be able to view those emails.
