From the symptom you are describing plus the diagnostic logs indicating "power on", I suspect the power adapter of the HDHomeRun is failing. The power adapter is likely shutting down causing the HDHomeRun to turn off completely, then everything tries to start back up again. The app doesn't like the ...

Checking, are you using the HDHomeRun FLEX with an attached USB drive? or are you using a NAS/PC for recordings?

What kind of drive are you using?

Found it - if the app can't determine the monitor the app is running on it returns null (by design) and UWP doesn't allow null to be marshaled which is weird.

It has been fixed, I will arrange for a new release quickly.

When does this error occur? (ie where in the app were you and what was the last action you did?)

Yes, you can use HDHomeRun guide data...

They should be the same number. The status.json number doesn't look right... we will get it fixed.

The firmware does not affect reception - it is not the problem.

IC7 - Richtek RT9081AGQZA

Suggestions:

1) Checking IC2 RT7273GQW:
Check +12V is reaching the input caps - C7, C8, and C9.
Check all 3 outputs. Easiest is to check L2 (1.8V), L3 (1.15V), and L5 (3.3V). If 1 or 2 rails are working it may be a short downstream on one rail rather than the IC that is ...

Checking, was the HDHomeRun app running when the computer was put to sleep? (trying to reproduce here)

When do you see this error (what actions led up to it)?

Improvements to subtitle support, including adding support for Australian subtitles.

We are fixing...

Very odd. Obviously they have internet access because the app update installed.

Are you running any special security software that could be interfering?

What iOS version?

A new Android / Fire release (20260713) has been submitted to the Amazon and Google app stores. It will take a day or so to come through.

They work fine on Android devices.

Problem reproduced on Shield. I will have an answer tomorrow.
