I recently acquired a Blackmagic Web Presenter 4K and have been experiencing an issue where it fails to stream to YouTube when connected through a Meraki network. The Web Presenter shows “On Air”, but no data reaches YouTube. However, it streams successfully to Twitch and Vimeo. If I switch to a direct internet connection (bypassing Meraki), it works fine. This suggests Meraki is blocking or interfering with Web Presenter’s RTMP/RTMPS traffic to YouTube. I thought this was a device fluke, but we purchased 4, have only unboxed 2, they both do the same thing. What I Have Tried So Far Checked Meraki Event Logs: No obvious blocks on a.rtmp.youtube.com or b.rtmp.youtube.com. No firewall rules explicitly blocking Web Presenter’s IP, set Web Presenter to White List in Meraki.  Tested With Different RTMP URLs: rtmp://a.rtmp.youtube.com/live2 → Failed rtmp://b.rtmp.youtube.com/live2 → Failed rtmps://a.rtmps.youtube.com/live2 → Failed rtmps://b.rtmps.youtube.com/live2 → Failed   Verified with OBS Studio: Using the same stream key & RTMP URL, OBS streams fine to YouTube, confirming that the problem is specific to Web Presenter’s connection through Meraki. I appreciate any help.  ... View more
