A message from XYZ couldn't be delivered - after 3 days offline

[kaktusztea]

After 3 days offline I started my second Signal Desktop app. It synced and there is a conversation where there are a bunch of "A message from XYZ couldn't be delivered".
XYZ is the nickname of the contact.
These error messages were the first after sync, then came the normal messages in order and well.

First OK message after errors (sent by me): 1679780205828

Platform Info

Signal Version: 6.11.0 (Win 10)

Linked Device Version: Ios 16.3.1

I can not get debuglog from my contact (XYZ) unfortunately.

This type of messages kept coming from this very contact. The solution was to delete the conversation.

1 year passed, didn't appear again, so I close this now.
