404 error when retrieving lineup information

[rkulagow]

I have hdhomerun-config installed; according to apt, it's the latest version.

Ubuntu v20.04, NextPVR Version: 5.0.4.200428 installed using the .deb package.

When adding my local OTA to the "B31" device below, I get a 404 error. 

The 404 error made me think that the issue was with Schedules Direct, but since I run Schedules Direct, I needed to look deeper.

Looking at the logs, I see:

The device in question:

HDHomeRun DUAL
Model: HDHR-US
Device ID: 10160B31
Firmware: 20200225

I saw that there was another thread with the same 404 error message, but I didn't see that the issue was resolved.

When you use a browser to hit the URL specified in the HDHOMERUN_TAG_LINEUP_URL, does it show you a list of channels?

I think something may have changed with legacy HDHR the logs look weird and so I tried with mine and get the same error. I don't even know what this call http://ip/lineup.xml?tuning on legacy is supposed to do.

Also I don't see any option to use ATSC or QAM either for HDHR but I don't know if that is supported.

I'll take a look at the code in a minute, to see if I can work out what is happening.

Out of curiosity though, was the other device working (ie, the non-legacy one)? 1310B768

When I tried that URL earlier, it wasn't working. It just returned some "null" text. That link now seems to return a channel list for me.

I wonder if SiliconDust had some temporary problem on their legacy lineup server? Can you try again in NextPVR just in case...

The non-legacy device works.

The legacy device is still returning a 404.

My link has been is working all along and I still get 404

What I think is weird in both our logs is it is going into a discovery scan and then it doesn't stop on the valid device.

You could see if this updated NShared.dll helps.

I think I might have broken legacy HDHR scanning recently when I made a change to work better with the Ceton HDHR simulator software

[mvallevand]

That breaks everything for me.
