Connecting to Whisper in Docker

Looking for some help.
HA running fine on RPI4/SSD. Have Voice / Assist running too (recent) - with local whisper/piper. Have Voice PE hardware running too.
Now trying to also get piper / whisper running on local container (on NAS) - to (a) compare performance and (b) learn how to ahead of perhaps getting beefier hardware.
Piper connected immediately when adding Wyoming service with NAS ip and port 10200. But Whisper (same container ip, port 10300) consistently errors - “failed to connect”.
So - as piper working fine - NAS ip and access to NAS containers working ok.
Containers seem to be running fine.

Any ideas on issue ?

My HA connects to my Whisper just fine. (It’s unusable on a Pi 4 because of performance, but that’s another issue.) How did you start Whisper? (docker run ...?)

Running whisper on container manager on Synology… so through UI. Have discovered it is erroring looking for something. Do I have to have the base-int8 file local to the container - I think I might do and thats what’s missing ?

This is how I run it:

docker run -d \
           -p 127.0.0.1:10301:10300 \
           -v /opt/ha-whisper/data:/data \
           rhasspy/wyoming-whisper \
           --model tiny-int8 --language en

I didn’t put anything in the data directory, it does that all by itself.

OK - brilliant - thank you. I have similar config parameters as you - but in a docker file… So you have helped confirm that’s its not the file but getting to the file on the hugging face repository.
Have disabled a bit of my firewall - and it now seems to work… ! So thank you for you help !
Now need to figure out why that was happening.
