Guys, We’ve got a stream coming from a third party which we’re using the Wowza Stream Engine’s MPEG-DASH Streaming Packetizer. On occasion we recieve a 404 error where the end client can’t find the manifest.mpd file. When I look at the error logs I see the following (see below). Please inform me as to what attributes, properties, etc I can adjust on the Wowza Stream Engine in order to remedy this issue. ```auto WARNservercomment2018-05-0315:16:04-----15110.988--------MPEGDashWriterHandler.startChunk[chunkIdHandler.onAssignChunkId][live/_definst_/cogoStream_source]: repeated chunk id 38 at timecode 113988 WARNservercomment2018-05-0315:16:06-----15113.692--------MPEGDashWriterHandler.startChunk[chunkIdHandler.onAssignChunkId][live/_definst_/cogoStream]: chunk ids skipping forward possibly due to dropped frames; previous chunk id: 38, nextChunkId: 40 at timecode 117659 WARNservercomment2018-05-0315:16:07-----15114.896--------MPEGDashWriterHandler.startChunk[chunkIdHandler.onAssignChunkId][live/_definst_/cogoStream_source]: chunk ids skipping forward possibly due to dropped frames; previous chunk id: 38, nextChunkId: 40 at timecode 117659 ERRORservercomment2018-05-0315:16:10-----128.72--------HTTPStreamerMPEGDashLiveIndex.indexFile[live/_definst_/cogoStream2160.smil] : java.lang.NullPointerException|at com.wowza.wms.httpstreamer.mpegdashstreaming.livestreampacketizer.MPEGDashWriterHandler.indexStream(MPEGDashWriterHandler.java:2544)|at com.wowza.wms.httpstreamer.mpegdashstreaming.livestreampacketizer.LiveStreamPacketizerMPEGDash.indexStream(LiveStreamPacketizerMPEGDash.java:224)|at com.wowza.wms.httpstreamer.mpegdashstreaming.file.HTTPStreamerMPEGDashLiveIndexItem.indexStream(HTTPStreamerMPEGDashLiveIndexItem.java:354)|at com.wowza.wms.httpstreamer.mpegdashstreaming.file.HTTPStreamerMPEGDashLiveIndex.indexFile(HTTPStreamerMPEGDashLiveIndex.java:444)|at com.wowza.wms.httpstreamer.mpegdashstreaming.httpstreamer.HTTPStreamerSessionMPEGDash.createIndexLive(HTTPStreamerSessionMPEGDash.java:85)| ERRORservercomment2018-05-0315:16:11-----129.289--------HTTPStreamerMPEGDashLiveIndex.indexFile[live/_definst_/cogoStream2160.smil] : java.lang.NullPointerException|at com.wowza.wms.httpstreamer.mpegdashstreaming.livestreampacketizer.MPEGDashWriterHandler.indexStream(MPEGDashWriterHandler.java:2544)|at com.wowza.wms.httpstreamer.mpegdashstreaming.livestreampacketizer.LiveStreamPacketizerMPEGDash.indexStream(LiveStreamPacketizerMPEGDash.java:224)|at com.wowza.wms.httpstreamer.mpegdashstreaming.file.HTTPStreamerMPEGDashLiveIndexItem.indexStream(HTTPStreamerMPEGDashLiveIndexItem.java:354)|at com.wowza.wms.httpstreamer.mpegdashstreaming.file.HTTPStreamerMPEGDashLiveIndex.indexFile(HTTPStreamerMPEGDashLiveIndex.java:444)|at com.wowza.wms.httpstreamer.mpegdashstreaming.httpstreamer.HTTPStreamerSessionMPEGDash.createIndexLive(HTTPStreamerSessionMPEGDash.java:85)| ERRORservercomment2018-05-0315:16:11-----129.852--------HTTPStreamerMPEGDashLiveIndex.indexFile[live/_definst_/cogoStream2160.smil] : java.lang.NullPointerException|at com.wowza.wms.httpstreamer.mpegdashstreaming.livestreampacketizer.MPEGDashWriterHandler.indexStream(MPEGDashWriterHandler.java:2544)|at com.wowza.wms.httpstreamer.mpegdashstreaming.livestreampacketizer.LiveStreamPacketizerMPEGDash.indexStream(LiveStreamPacketizerMPEGDash.java:224)|at com.wowza.wms.httpstreamer.mpegdashstreaming.file.HTTPStreamerMPEGDashLiveIndexItem.indexStream(HTTPStreamerMPEGDashLiveIndexItem.java:354)|at com.wowza.wms.httpstreamer.mpegdashstreaming.file.HTTPStreamerMPEGDashLiveIndex.indexFile(HTTPStreamerMPEGDashLiveIndex.java:444)|at com.wowza.wms.httpstreamer.mpegdashstreaming.httpstreamer.HTTPStreamerSessionMPEGDash.createIndexLive(HTTPStreamerSessionMPEGDash.java:85)| ERRORservercomment2018-05-0315:16:12-----130.42--------HTTPStreamerMPEGDashLiveIndex.indexFile[live/_definst_/cogoStream2160.smil] : java.lang.NullPointerException|at com.wowza.wms.httpstreamer.mpegdashstreaming.livestreampacketizer.MPEGDashWriterHandler.indexStream(MPEGDashWriterHandler.java:2544)|at com.wowza.wms.httpstreamer.mpegdashstreaming.livestreampacketizer.LiveStreamPacketizerMPEGDash.indexStream(LiveStreamPacketizerMPEGDash.java:224)|at com.wowza.wms.httpstreamer.mpegdashstreaming.file.HTTPStreamerMPEGDashLiveIndexItem.indexStream(HTTPStreamerMPEGDashLiveIndexItem.java:354)|at com.wowza.wms.httpstreamer.mpegdashstreaming.file.HTTPStreamerMPEGDashLiveIndex.indexFile(HTTPStreamerMPEGDashLiveIndex.java:444)|at com.wowza.wms.httpstreamer.mpegdashstreaming.httpstreamer.HTTPStreamerSessionMPEGDash.createIndexLive(HTTPStreamerSessionMPEGDash.java:85)| WARNservercomment2018-05-0315:16:13-----15120.908--------MPEGDashWriterHandler.endChunk[live/_definst_/cogoStream_360p]: Stream start time calculation is off by 2337ms from original value.
