Emby Server is not waking to record programs

[Noel-M 11]

Emby server has been working well for me for the past several years.  Recently, some recorded programs are not complete.  The first 15 minutes or so is missing.  My server is mostly asleep and only wakes to record or play back.

Logfiles are attached.  Here is such an incident …

* Program Maigret will record in 18 minutes

* However, 2 minutes before the recording starts, the server goes to sleep

* The windows power report (screenshot attached) shows that the server is woken to perform the recording at 20:28  (09:28 GMT)

* Emby does not respond until 20:43

Hi, how are your system sleep settings set?

[Noel-M 11]

Hi Luke,

Its Windows 11, sleep after 15 minutes, hibernate never.

I've been using Windows 11 for 6 months (ish) and have only just started noticing this - maybe about once a week.

I seem to recall that in WIndows 10 I had "unattended sleep timeout" set, but I haven't checked this in windows 11.  Relevant ??

[Noel-M 11]

The unattended sleep timeout was 8 minutes.  I changed it to 15.  Will let you know if it makes a difference.
