In Issue #9561, the self-hosted server is off when the problem occurs, so I think that is a substantial difference versus what users in this thread are reporting.
Therefore, I think the best course of action is to start a New Issue on GitHub, and reference Issue #9561 from your issue; linking this Community Forum thread would also be advisable.
@Nemesis @Bryan_Prajugo @Loganizzi @KheKit @Ishi I would encourage any one of file a bug report (New Issue) on GitHub, or contribute to the discussion if someone else has posted the issue before you.
