But unless there's a recording at exactly the same time, you
must use 5072 for this preview. I'd have expected to see
something in the BE log for this:

     ... HttpServer50 services/content.cpp:524 (GetPreviewImage) - GetPreviewImage: No recording ...

Also, the initial lookup is in the DB, which now stores the starttime (and others)
in UTC. Hopefully you used a recording that already displays a preview for your
1st attempt (as suggested.) After you know that the GetPreviewImage endpoint works,
then looking for your old (non preview generating) image based on the filename means
that you'll have to adjust the filename's timestamp to UTC, remembering to include
DST in that adjustment. Or, you can get it out of the DB or use:

     MyServer:6544/Dvr/GetRecordedList

from you browser and use its search feature to find the recording and get the
timestamp from there.
