# Meshcast connection issues

If guests can’t see/hear each other or director tiles spin when using `&meshcast`, try these:

* Change region: Pick a different Meshcast server (`&meshcastcode=use1`, `usw1`, `de1`, etc.). Servers can be busier at local peak times.
* Codec swap: Try `&meshcastcodec=h264` or `vp9` for compatibility; for screen shares, adjust `&mcscreensharecodec=`.
* Bitrate caps: Reduce video/audio bitrate to stabilize (`&meshcastbitrate=2000`, `&meshcastaudiobitrate=64`), and lower screen‑share bitrate if needed (`&mcscreensharebitrate=`).
* Fallback path: If a specific viewer struggles, add `&nomeshcast` to their view link to request a direct P2P feed from that publisher when possible.
* Director preview: Avoid opening many high‑bitrate views in the director at once; use scene or single‑view previews where possible.
* Alternate route: If enterprise networks interfere, consider WHEP/WHIP for viewers or use `backup.vdo.ninja` as a quick test.
