Unclassified failure
Report this code, the failed stage and the detailed reason.
REPC-1001Sign-in failed or required
Check your sign-in details and sign in again.
REPC-1002Connection or action not authorized
Check the host's access, tier and approval settings with its owner.
REPC-1003Backend request failed
Check the API response and connectivity to the forpro-remote server, then retry.
REPC-1004Host unavailable
Refresh the computer list and check that the host is online and sharing.
REPC-1005Host approval failed
Ask the host owner to check the connection request and retry.
REPC-1006Host approval timed out
Retry while the host owner is available to approve the request.
REPC-1007Invalid backend response
Record the response reason and check that app and server versions are compatible.
REPC-2001Direct route discovery failed
Check LAN discovery and STUN/NAT observations on both PCs. A STUN failure alone does not prove UDP is blocked.
REPC-2002Direct UDP connection failed
Check the host, route and app-specific UDP firewall rules on both PCs.
REPC-2003UDP punch timed out
Compare both PCs' route/punch logs and NAT configuration; the timeout does not identify the blocking device.
REPC-2004Secure handshake timed out
Check both peers' handshake and identity logs, then retry.
REPC-2005Host identity or session trust failed
Verify the host identity and session authorization. Do not bypass certificate verification.
REPC-2006Local UDP port unavailable
Check which local process owns the requested UDP port and retry with an available port.
REPC-2007Active connection ended unexpectedly
Check whether the host stopped or either network changed, then reconnect.
REPC-3001Remote renderer initialization failed
Check the client GPU driver and renderer backend in the detailed reason.
REPC-3002Video decoder initialization failed
Check the client codec runtime and GPU support; try a supported codec and pixel format.
REPC-3003Host display capture failed
On the host, check the selected display, screen-capture permission and capture backend.
REPC-3004Host video encoding failed
Check the host encoder runtime and driver; retry with supported resolution, codec and HDR settings.
REPC-3005Virtual display operation failed
Check the host VDD driver, display topology and ADD/SELECT acknowledgement.
REPC-3006No first video packet
Compare host capture/encode/send counters with client receive counters.
REPC-3007No complete first video frame
Check packet loss, frame assembly and stale-frame counters on the client.
REPC-3008Video decode failed or stalled
Compare assembled and decoded frame counters and inspect the decoder error.
REPC-3009Decoded video not presented
Check rendered-frame counters, the client window and GPU presentation errors.
REPC-4001Audio operation failed
Check audio device selection, permissions and the capture/playback error.
REPC-4002Input operation failed
Check input permissions and the host interactive input helper.
REPC-4003Virtual gamepad operation failed
Check the host ViGEmBus driver and virtual-controller connection result.
REPC-4004Operating-system permission required
Grant the permission named in the reason in OS settings, then retry.
REPC-5001Remote process launch failed
Check that the installed executable and runtime files are available.
REPC-5002Remote process exited before first frame
Collect the child process log and crash report; the last stage is only an observation.
REPC-5003Stage completion not reported in time
Inspect the last stage and its counters; check the child process before retrying.
REPC-5004Settings operation failed
Check the setting value, device support and host acknowledgement.
REPC-5005Local file or IPC operation failed
Check storage space and access to the forpro-remote state directory.
REPC-5006Host startup failed
Check the host service/process log and the failed startup component.
