We are trying to send a test video stream directly from Aximmetry via RTMP. However, we are encountering repeated errors in the log:

- "Failed to create file: I/O error

- "Failed to stream video to rtmps://…:443/app/…"

- "Error writing audio frame: I/O error"

- "Error closing file: I/O error"

We are using an RTMPS endpoint (AWS IVS-style URL). The same RTMP/RTMPS URL and stream key work without any issues on the same machine when using Wirecast, so we can likely rule out network, firewall, or credential problems.
