AppleTV cannot direct play MKV DV (Profile 5)

Server Version#: 1.41.2.9200 Player Version#: 8.43 Hi, I have a mkv file with Dolby Vision (profile 5). Last week I was able to play it without problem on my AppleTV. No issues, Direct Play. This week is giving me an error that cannot direct play nor transcode the file. iPhone can Direct Play without issues. What could have happened?
