Unable to detect HDHR Connect Quatro

[daphatty]

As the title states - NPVR is unable to detect the HDHR Connect Quatro running on my network.

I am running NPVR via Synology Docker. I ran through the install instructions twice, once with and once without the additional -env setting. Neither installation could detect my HDHR. The log snippet below shows the HDHR never seems to respond to the query. Perhaps I missed something during setup?  The current container settings are attached.

Why aren't you use the current docker release?

 I could swear I had the latest. Or, at least I assumed I'd get the latest version by downloading from Docker Hub?

EDIT: Looks like Docker Hub is a month old...

https://registry.hub.docker.com/r/nextpv...pvr_amd64/

[mvallevand]

There is a version called latest which isn't. You want to use the version called stable.

Martin

[daphatty]

Switched to Stable.  Still a challenge, although now with a different error.

Code:

[1] Error discovering HDHR devices: The operation has timed out.
[1]
[1] Unexpected error with HDHR discovery: Newtonsoft.Json.JsonReaderException: Error reading JArray from JsonReader. Path '', line 0, position 0.
   at Newtonsoft.Json.Linq.JArray.Load(JsonReader reader, JsonLoadSettings settings)
   at Newtonsoft.Json.Linq.JArray.Parse(String json, JsonLoadSettings settings)
   at NShared.Utility.HDHomeRun.Discover(String specificDeviceID)

Side note - I noticed sub's instructions actually contain "latest" in the docker run command code.

Code:

docker run -d \
    --name nextpvr \
    --volume /home/pi/config:/config \                   
    --volume /home/pi/videos:/recordings \
    --volume /home/pi/videos:/buffer \
    --restart unless-stopped \
    --publish 16891:16891/udp \
    --publish 8866:8866 \
    nextpvr/nextpvr_amd64:latest

Two other places in the same post said "nextpvr/nextpvr_amd64: stable". I must have forgot to correct this other mention of it. I've fixed it fixed it now though.

Does this url return your list of HDHomeRun devices?

http://ipv4-api.hdhomerun.com/discover

Yes.

For some reason, it looks like your docker instance is unable to get to that url:

Any chance I may need to open additional ports?
