Hi, I’m having an issue where the first time I try to connect to an MPEG DASH stream, it fails. In looking at the Chrome network inspector, I see I get 404s on various requests. When I reconnect, it works fine, and subsequent reconnects are also fine, unless (it seems) the stream hasn’t been viewed for a bit, in which case the connection fails again. Any idea what the problem could be? Thanks, Rhys ---

Hello, Would you please further describe the workflow? If this is this a [origin/edge repeating](https://www.wowza.com/docs/how-to-configure-a-live-stream-repeater) workflow using the default “on demand” mode? If so, you may want to look into using [“persistent mode”](https://www.wowza.com/docs/scaling-with-wowza-live-stream-repeater) between servers to avoid the stream startup delay caused as the manifest files are built. You could also look into using the free [ModuleLoopUntilLive](https://www.wowza.com/docs/how-to-loop-a-pre-roll-until-a-live-stream-starts-loopuntillive) to keep your stream active even if the source stream is not present. This can help if the issues are caused by an intermittent source stream. Best regards, Andrew
