# 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.

Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.vdo.ninja/common-errors-and-known-issues/meshcast-connection-issues.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
