Description

Mistserver complains about a file that works most of the time but occasionally fails with this:
```
305 [2022-10-18 04:26:36] MistInMP4:catalyst_vod_eefaghda (2632) FAIL : Error getting URI info for 'https://storage.googleapis.com/alex k-dms-upload-test/test-emran/new/10s.mp4.dtsh': 404 Not Found
306 [2022-10-18 04:26:36] MistInMP4:catalyst_vod_eefaghda (2632) FAIL : No MOOV box found; aborting header creation!
307 [2022-10-18 04:26:36] MistInMP4:catalyst_vod_eefaghda (2632) FAIL : Reading header for 's3+https://GOOG1EXCXWNKVLKBEJS62OMGXMQ5C5FH 67YZMQXYGFBQYQRBYXQQJT5OM6L4I:rzM9CFtiunoflGzBwU3c%2FOBw9D5hy0Ntb mmedu6x@storage.googleapis.com/alexk-dms-upload-test/test-emran/n ew/10s.mp4' failed.

Research direction

Start with the attached moov.log and the MistInMP4 error sequence, then compare the failing Google Cloud Storage request with a successful request for the same file. The issue names no source file or test, so first locate the code handling the MOOV/header request path. Done means the intermittent failure is reproducible, its cause is identified, and the file is processed without the MOOV error.
