MF_E_NET_PROXY_TIMEOUT

MF_E_NET_PROXY_TIMEOUT means the proxy waited too long for the upstream media server. The client may be healthy while the proxy-to-origin leg is slow, blocked, or overloaded.

What to check

  • Compare client-to-proxy and proxy-to-origin latency.
  • Review upstream timeout values only after identifying why the origin is slow.
  • Check for packet loss, route problems, and overload on the origin or proxy.
